Case Report: A case report of acromegaly associated with primary aldosteronism
Authors: Matrozova Joanna , Vandeva Silvia , Zacharieva Sabina
Published: February 2014

We describe a patient with a rare combination of acromegaly and primary aldosteronism. A 37 year-old female patient was diagnosed with acromegaly on the basis of typical clinical, hormonal and image characteristics. She presented also with one of the most common co-morbidities – arterial hypertension. The patient has been regularly followed-up and after three surgical interventions, irradiation and adjuvant treatment with a dopamine agonist, acromegaly was finally controlled in 2008 (20 years after diagnosis). Arterial hypertension however, remained a therapeutic problem even after prescription of four antihypertensive drugs. She had normal biochemical parameters, except for low potassium levels 3.2 (3.5-5.6) mmol/l. This raised the suspicion of primary hyperaldosteronism, confirmed by a high aldosterone to plasma rennin activity ratio, high aldosterone level after a Captopril challenge test and visualization of a 35 mm left adrenal nodule on a CT scan. After an operation, the patient recovered from hypokalemia and antihypertensive therapy was reduced to a small dose of a Ca blocker.

Co-morbid arterial hypertension is common in acromegaly, though it is rare for this to be caused by Conn’s adenoma. The association of Conn’s adenoma with acromegaly has been interpreted in two lines: as a component of multiple endocrine neoplasia type (MEN1) syndrome or as a direct mitogenic effect of hyperactivated GH-IGF1 axis.

Audience responses to environmental fiction and non-fiction films
Authors: Brereton Pat , Hong Chao-Ping
Published: February 2014

Having been closely involved with developing a textual analysis strategy for examining ecology within Hollywood fiction, it has become necessary to test some of the hypotheses and assertions embedded in such analysis and explore how actual audiences perceive and decode ecocinema. Consequently in this small pilot study of communications students at Dublin City University, using pilot survey/questionnaires, discussion groups and the Q-methodology, we have tried to tease out the relative benefits and usage of such methods with the aim of producing some tentative findings, which will be explored and tested across further studies over the next few years. In particular this article focuses on comparing audience perspectives using non-fictional as against fictional evocations of an environmental agenda.

The non-human and affect in Seven Minutes in the Warsaw Ghetto
Authors: Walden Victoria Grace
Published: February 2014

Seven Minutes in the Warsaw Ghetto uses non-human figures and a non-realist aesthetic to engage us in an affective, embodied experience. Our momentarily tragic encounter with history is shaped by difference and otherness and thus we sense our distance from the past while glancing at a history we cannot grasp.
Can what is beyond imagining be represented on-screen?
Authors: Lefebvre-Linetzky Jacques
Published: February 2014

Representing the Holocaust raises fundamental questions regarding the almost impossible task of reproducing a specific ‘reality’ on-screen. Animation provides an environment that is both realistic and metaphoric and thus it enables the viewer to imagine the claustrophobic reality of life in the Warsaw Ghetto and access an emotional truth.

Created substrates do not fully mimic natural substrates in restoration: the occurrence of polypores on spruce logs
Authors: Komonen Atte , Halme Panu , Jäntti Mari , Koskela Tuuli , Kotiaho Janne , Toivanen Tero
Published: February 2014

Many protected areas have been under intensive forest management prior to protection and thus lack natural ecosystem structures and dynamics. Dead wood is a key structure in forests harboring hundreds of threatened species. We investigated the ecological success of dead wood creation as a boreal forest restoration measure. We analysed whether the polypore communities of chain-saw felled and girdled (subsequently fallen) Norway spruce ( (L.) H. Karst.) logs differ from naturally formed spruce logs of similar decay stage and size. The study was conducted in LeivonmÃ¤ki National Park in central Finland 8 years after the restoration measures. The average number of polypore species was highest on the chain-saw felled logs and most of the common polypore species were most frequent on this substrate. However, among the natural logs, number of species increased more steeply with increasing number of logs, suggesting greater variation in community composition on this substrate. The old-growth forest indicator occurred frequently on natural logs, occupied a few girdled logs but was absent from chain-saw felled logs. Our results show that from the polypore perspective created logs do not fully mimic natural logs, suggesting that creating substrates for species may pose a challenge for restoration.Picea abiesPhellinus ferrugineofuscus

Published: February 2014

The aim of the present study was to evaluate histologically vertical bone regeneration outcomes after using bovine bone graft material in block and granular forms. The buccal bony plates of the outer mandibles of 10 New Zealand rabbits received Bio-Oss blocks that were immobilized using orthopedic mini-plates, and another 10 received granular forms that were gently packed and stabilized into the custom-made perforated metallic cubes. The mean graft area (GA), new bone area (NBA), bone-to-graft contact (BGC), and maximum vertical height reached by the new bone development (MVH) were histometrically evaluated and showed no significant differences between 2 graft types. The new bone was observed mostly close to the basal bone and developed penetrating the trabecular scaffold in the form of seams that covered the intralumen surfaces of the block type graft, while in the granular graft type the new bone was observed to grow between the graft particles usually interconnecting them. Either form of Bio-Oss was capable of providing considerable vertical bone augmentation.

Authors: Almeida Jr. Hiram Larangeira de , Monteiro Luciane , Silva Ricardo Marques e , Rocha Nara Moreira , Scheffer Hans
Published: February 2014

In dystrophic epidermolysis bullosa the genetic defect of anchoring fibrils leads to cleavage beneath the basement membrane, with its consequent loss. We performed scanning electron microscopy of an inverted blister roof of a case of dystrophic epidermolysis bullosa, confirmed by immunomapping and gene sequencing. With a magnification of 2000 times a net attached to the blister roof could be easily identified. This net was composed of intertwined flat fibers. With higher magnifications, different fiber sizes could be observed, some thin fibers measuring around 80 nm and thicker ones measuring between 200 and 300 nm.
Randomized clinical efficacy of superficial peeling with 85% lactic acid versus 70% glycolic acid
Authors: Prestes Paula Souza , Oliveira Márcia Motta Maia de , Leonardi Gislaine Ricci
Published: February 2014

BACKGROUND: Peeling is a procedure which aims to accelerate the process of skin exfoliation. OBJECTIVES: Development of formulations containing lactic acid at 85% or glycolic acid at 70% and the evaluation of these formulations on clinical efficacy in reduction of fine wrinkles. METHODS: Preliminary stability tests were carried out and an in vivo study was performed with three groups with 9 representatives each. One was the control group, which used only sunscreen; another one used lactic acid+sunscreen, and the last group used acid glycolic+sunscreen. Clinical efficacy was assessed with a CCD color microscope, through the digitization of images before and after treatment. The applications were carried out by a dermatologist, once a mont h every 30 days, during 3 months. The area with wrinkles was calculated by planimetry point counting, in accordance with Mandarin-de-Lacerda. RESULTS: The formulations were stable in the visual and Ph evaluation. There was no improvement in the control group; for lactic acid, there was significant improvement after the second peeling application on the outer lateral area of the right eye and after the third application on the outer lateral area of the left eye. For the glycolic acid group, there was significant improvement in the outer lateral area of the left eye after the first application, and of the right eye region, after three applications. The formulations used must be kept under refrigeration and should be manipulated every 30 days. CONCLUSIONS: Both peelings were effective in reducing fine wrinkles of the outer lateral eye area after three applications (p≤0.05%). It was observed that peeling efficacy in the external-lateral region of one eye might be different compared with that in skin of the external-lateral region of the other eye, relative to the speed of skin improvement.

Published: February 2014

BACKGROUND: Based on personal observations of dermatologists, nutritionists and patients, a new problem emerges in the gyms: development and exacerbation of acne in users of whey protein, which is a protein derived from cow's milk. Whey Protein extract contains growth factors that may be related to acne. Its purity and composition are not fully known and there is no scientific research on its potential to cause acne. OBJECTIVES: Assess the relationship between the use of proteincalorie supplements and onset or exacerbation of acne vulgaris in young adults in the city of João Pessoa. METHODS: Descriptive observational study conducted in gyms and in a dermatology clinic. Each participant was examined for acne on three occasions and followed for 60 days. RESULTS: 30 patients were examined. Onset or exacerbation of acneiform lesions were observed (p <0.0005). The effect was more prominent in females and in individuals without current acne and no family history of acne. CONCLUSION: This study showed the onset of acne with the progressive use of protein-calorie supplementation, in a two-month period. It is suggested that this type of supplementation be discouraged.

Published: February 2014

BACKGROUND: Prevalence of tattoos is around 10-26% in men and 10-22% in women, and can involve negative effects such as: regret, removal attempts, physical and biological changes of the skin and association with some viral diseases. OBJECTIVE: to determine the prevalence, characteristics and factors associated with tattoos in recruiters joining the military. METHODS: the recruiters were examined by dermatologists that documented the presence or absence of tattoos, as well as their sizes, colors, designs and patterns, and whether they needed a parent's consent to get a tattoo. RESULTS: 1,968 recruiters were examined and the prevalence of tattoos was 10.82% (213), 141 (66.20%) had a single tattoo, 44 (20.66%) two tattoos, 15 (7.04%) three tattoos, 9 (4.23%) four tattoos, and 4 (1.88%) had more than four. Of the total sample, 168 (80.77%) reported getting the first tattoo before the age of 18. 158 (74.53%) were monochromatic. In relation to size, 108 (50.70%) had tattoos of up to 10 cm, 75 (35.21%) had tattoos measuring between 11-20cm, while 30 had ones over 21cm (14.09%). CONCLUSIONS: The population studied had a high prevalence of tattoos for their age, the percentage of complex (large and polychromatic) tattoos was also high.

Published: February 2014

Dermatoscopy of melanocytic lesions has guided the decision of when or not to biopsy a lesion. The use of this tool has increased clinical examination's sensitivity and specificity in 89% and 96% respectively. However, dermatoscopic evaluation of amelanotic or hypomelanotic melanomas, as well as metastases, can be difficult. There is still no standardization for the analysis of these pathologies, which relies mostly on their vascular pattern. We describe the dermatoscopy of acral metastatic amelanotic melanoma.

POEMS syndrome is a unique clinical entity, the diagnosis of which is made when polyneuropathy and monoclonal gammopathy occur together, associated with other changes such as organomegaly, endocrinopathy, skin changes and papilledema. Cutaneous manifestations are heterogeneous, with diffuse cutaneous hyperpigmentation, hemangiomas and hypertrichosis occurring more frequently. We report the case of a 65- year-old female patient with this syndrome, diagnosed after 15 years of disabling peripheral neuropathy.
Hypopigmented mycosis fungoides: a review of its clinical features and pathophysiology
Authors: Furlan Fabricio Cecanho , Sanches José Antonio
Published: February 2014

Several distinct clinical forms of mycosis fungoides have been described. Hypopigmented mycosis fungoides should be regarded as a subtype of mycosis fungoides, insofar as it presents some peculiar characteristics that contrast with the clinical features of the classical form. Most patients with hypopigmented mycosis fungoides are younger than patients typically diagnosed with classical mycosis fungoides. In addition to typical dark-skinned individuals impairment, hypopigmented mycosis fungoides has also been described in Asian patients. The prognosis for hypopigmented mycosis fungoides is much better than for classical mycosis fungoides: hypopigmented mycosis fungoides is diagnosed when there are only patches of affected skin, and lesions usually will not progress beyond terminal stages, although they can persist for many years. Diagnosis should involve clinicopathologic correlation: skin biopsy analysis often reveals intense epidermotropism, characterized by haloed, large, and atypical CD8+ lymphocytes with convoluted nuclei, in contrast to mild to moderate dermal lymphocytic infiltrate. These CD8+ cells, which participate in T helper 1-mediated immune responses, prevent evolution to mycosis fungoides plaques and tumors and could be considered the main cause of the inhibition of melanogenesis. Therefore, hypopigmentation could be considered a marker of good prognosis for mycosis fungoides.

Langerhans cell histiocytosis is a rare, clinically heterogeneous desease. Since there is considerable clinical overlap among the four described variants (Hand-Schüller-Christian, eosinophilic granuloma, Letterer-Siwe and Hashimoto-Pritzker), the concept of spectral disease applies to this entity. The Hashimoto-Pritzker variant was first described in 1973. Characteristically, it is present at birth or during the first days of life, impairment is limited to the skin and prognosis is favorable with spontaneous resolution. We report a newborn male patient with Hashimoto-Pritzker disease presenting as a S100 + and CD1a + single congenital perianal lesion with rapid involution in two months.

Published: February 2014

Psoriasis is a polygenic, inflammatory and progressive disease, characterized by an abnormal differentiation and hyperproliferation of keratinocytes, associated with impaired immunologic activation and systemic disorders, while psoriatic arthritis is a chronic inflammatory articular disease. Pathophysiology of psoriasis comprises a dysfunction of the immune system cells with an interactive network between cells and cytokines supporting the initiation and perpetuation of disease and leading to inflammation of skin, enthesis and joints. Recent studies have shown an important role of systemic inflammation in the development of atherosclerosis. Corroborating these findings, patients with severe Psoriasis have marked incidence of psoriatic arthritis, cardiovascular diseases, hypertension, dyslipidemia, obesity and diabetes mellitus, showing an increased risk for acute myocardial infarction, which suggests that the condition is not restricted to the skin. Nuclear receptors are ligand-dependent transcription factors, whose activation affects genes that control vital processes. Among them the peroxisome proliferator-activated receptor is responsible for establishing the relationship between lipids, metabolic diseases and innate immunity. In the skin, peroxisome proliferator-activated receptors have an important effect in keratinocyte homeostasis, suggesting a role in diseases such as psoriasis. The peroxisome proliferator-activated receptors agonists represent a relevant source of research in the treatment of skin conditions, however more clinical studies are needed to define the potential response of these drugs in patients with psoriasis and psoriatic arthritis.

Cutaneous abscess is a localized collection of pus in the dermis and subcutaneous tissue usually caused by trauma. The authors report the case of a 30-year-old male patient, gardener, that presents an ulcerated plaque in the third right finger, caused by an aculeus plant wound. The examination of the lesion's exudate ruled out the existence of fungi and showed the presence of Staphylococcus aureus. The authors emphasize the sporotrichosis as an important differential diagnosis, especially in endemic areas, and the indication of the exudate culture is discussed.

Foi realizado um estudo retrospectivo de janeiro de 2008 a dezembro de 2012 com base nos laudos de necropsia do Laboratório de Anatomia Patológica (LAP) da Faculdade de Medicina Veterinária e Zootecnia (FAMEZ), Universidade Federal de Mato Grosso do Sul (UFMS), com o intuito de descrever quais as doenças que afetam o sistema nervoso de bovinos que ocorrem no Mato Grosso do Sul. Os casos consistiam de acompanhados por técnicos do LAP e encaminhados por médicos veterinários que atuam no campo (autônomos ou do serviço veterinário oficial). De 1082 materiais analisados, 588 apresentavam histórico de sinais clínicos neurológicos. Destes, 341 (53,75%) tiveram diagnóstico correspondente a doenças neurológicas e 247 (46,25%) tiveram diagnóstico inconclusivos. As fichas clínico epidemiológicas foram revisadas para determinar dados referentes a epidemiologia, aos sinais clínicos e às alterações macroscópicas e microscópicas. O botulismo (16,67%), a raiva (15,92%), a polioencefalomalacia (8,05%) e a encefalite por herpesvirus bovino (4,31%) foram as enfermidade de maior frequência. Outras doenças como meningoencefalite não supurativa (2,62%), meningoencefalite supurativa (1,50%), abscessos cerebrais e osteomielite por compressão medular (1,31%), tétano (1,12%), hipotermia (0,94%), babesiose cerebral (0,75%), febre catarral maligna (0,37%) e lesões sugestivas de intoxicação por oxalato (0,19%) foram ocasionalmente diagnosticadas. Em nenhum dos casos foram observadas lesões que pudessem sugerir encefalopatia espongiforme bovina.

Published: February 2014

Descrevem-se 14 casos de condrodisplasia em bovinos. Os dados epidemiológicos e clínicos foram obtidos de protocolos de necropsia e o estudo histológico das lesões foi realizado em fragmentos de ossos longos e ossos da base do crânio dos 14 casos estudados. Onze casos eram de condrodisplasia tipo Telemark e três, tipo bulldog (Dexter). Treze dos 14 bovinos afetados eram da raça Jersey e um era da raça Shorthorn. Concluiu-se que o gene transmissor das condrodisplasias encontra-se presente na população Jersey da região e medidas, como utilização de reprodutores de outras regiões e/ou com teste de progênie ou identificação de genes indesejáveis por meio de técnicas moleculares, devem contribuir para diminuir a ocorrência destes casos na população Jersey da região.

Published: February 2014

A evolução tecnológica tem possibilitado o desenvolvimento e o aperfeiçoamento de novos materiais para implantes. Apesar dos fundamentais benefícios providos pelos dispositivos ortopédicos, complicações decorrentes de corrosão, degradação, infecção, além de outras podem ocorrer. O entendimento das características dos biomateriais é fundamental para a previsibilidade do seu comportamento in vivo, fornecendo subsídios para que o composto mais adequado seja escolhido na reconstrução do defeito ósseo. As placas de origem metálica são as mais utilizadas para o reparo de fraturas de ossos longos, sendo mecanicamente resistentes e biocompatíveis. No entanto, a necessidade de remoção e o enfraquecimento do osso são suas principais desvantagens. Neste trabalho, placas produzidas a partir de osso cortical equino foram empregadas experimentalmente em fêmur osteotomizado de coelhos (Grupo osso-GO), num estudo comparativo com placas de metal (Grupo metal-GM). A avaliação radiográfica foi realizada a cada 30 dias, durante 120 dias, momento em que foi então realizada análise histológica do material em estudo. Não houve diferença estatisticamente significante entre os dois grupos com relação à morfometria do calo ósseo e consolidação óssea em todos os momentos avaliados, sendo que ambas as placas permitiram a consolidação em todos os animais. Entretanto, observou-se que o calo ósseo foi menor no GO, em relação ao GM, em todos os momentos do estudo. Por outro lado, a maior parte dos animais do GO apresentou consolidação completa da fratura aos 90 dias, enquanto que no GM isto ocorreu aos 60 dias. Não foram evidenciadas células do tipo corpo estranho na histopatologia dos animais do GO, mas maior quantidade de tecido fibroso foi identificada, envolvendo este biomaterial. A placa confeccionada com osso equino representa uma alternativa de baixo custo e muito viável, uma vez que permitiu estabilização adequada para consolidação óssea de fratura de fêmur em coelhos. Neste estudo, a menor formação de calo periosteal, associada a um tempo superior para consolidação em GO sugerem maior estabilidade da fratura onde a placa de osso foi utilizada.

The study examined (1) the immune response in broiler chickens after oral immunization with recombinant flagellin (rFliC) from Salmonella Typhimurium conjugated with sodium alginate microparticles, and the immune response enhancement in association with recombinant cholera toxin B subunit protein (rCTB) and pool of Lactobacillus spp. (PL). The immune responses were evaluated by dosage of IgY serum and IgA from intestinal fluid and immunostaining of CD8+ T lymphocytes in the cecum. The immunized animals were challenged with Salmonella Typhimurium (ST) 21 days after treatment. In all immunized groups, a significant increase (p<0.05) was observed in IgA levels (μg/mL), especially three weeks after immunization. The serum IgY levels (μg/mL) were little affected by the treatments and differed significantly among groups only in the second post-immunization week (p<0.05). After the challenge, the number of CD8+ T cells differed significantly between the treatments and negative control. Retrieval of Salmonella Typhimurium was not detected at 48 hours after the challenge in T2 (rFliC+rCTb), T3 (rFliC+PL) and T4 (rFliC+rCTB PL). The rFliC administered orally with or without rCTB and Lactobacillus spp. produces significant induction of humoral immune response, and the immunized chickens were more effective in eliminating Salmonella after challenge.

Published: February 2014

A intoxicação experimental por Trema micrantha em cinco ovinos é descrita. Quatro ovinos apresentaram sinais clínicos respiratórios acentuados e morte após ingestão da terceira dose de folhas da planta. As manifestações clínicas mais frequentes nesses casos foram taquipneia, dispneia, retração ritmada das narinas, mucosas cianóticas, corrimento nasal mucoso, hipertermia, aumento de volume abdominal bilateral e na região parotídea, incluindo crepitação à palpação, membros lateralmente afastados ao caminhar e decúbito esternal. T. micrantha mostrou-se tóxica para ovinos na dose de 20-50g/kg de peso animal. Na necropsia desses ovinos foram observados, além das mucosas cianóticas, enfisema subcutâneo em região cervical ventral ou porção mediastinal dorsal, pulmões não colabados, pesados, com impressão das costelas na superfície e conteúdo espumoso vermelho em traqueia e brônquios, além de múltiplas petéquias subpleurais. Na avaliação histológica predominaram alterações pulmonares, com espessamento de septos alveolares por proliferação difusa de pneumócitos tipo II, conferindo aspecto adenomatoso a algumas áreas. Os pneumócitos apresentavam núcleo volumoso, hipercromático, ora bizarro ou eram multinucleados, com nucléolos evidentes e, em algumas áreas, os pneumócitos estavam descamados para a luz alveolar, ora formando sincícios. Havia também proliferação do epitélio bronquiolar, com formação de mais de uma camada celular, núcleos hipercromáticos e volumosos e redução na quantidade de cílios. As alterações proliferativas dos pneumócitos e do epitélio bronquiolar foram evidenciadas pela imunomarcação anti-citoqueratina e anti-Ki-67 e, para a diferenciação entre pneumócitos e macrófagos alveolares, foi empregada imuno-histoquímica anti-mieloide/histiócitos (MAC387). Um ovino apresentou quadro clinico-patológico de insuficiência hepática aguda, com necrose hepatocelular acentuada após ingestão de 25g/kg de T. micrantha. A intoxicação experimental por T. micrantha em ovinos resultou em quadro clinico-patológico, predominantemente, respiratório na maioria dos casos, confirmando os resultados observados em casos de intoxicação espontânea.

The study aimed to quantify the concentrations of free IGF-I in serum and fluid of ovarian follicles in pre-pubertal gilts and describe the ovarian morphology by measuring the size of the ovaries and counting the number of surface follicles. Ovaries (n=1,000) from pre-pubertal gilts were obtained immediately after slaughter. A total of 10 samplings were performed, with ovaries obtained from 50 females for each collection. The follicles situated on the surface of each ovary were classified as small (SFs, 2 to 5mm in diameter) or large (LFs 6 to 10mm in diameter) and the follicular fluid was obtained by follicle aspiration. The collection of serum samples was performed after the gilts exsanguination using sterile tubes. From the pool of serum and follicular fluid obtained from 50 females, the concentration of free IGF-I was determined in each sample using an enzyme immunoassay kit (ELISA). The description of ovarian morphometry was performed in 100 ovaries from randomly selected gilts. The larger and smaller lengths of ovaries were measured, and the total number of SFs and LFs present on the surface of each ovary were also counted. The IGF-I concentration was greater (P<0.05) in LFs (170.92±88.29 ng/mL) compared with SFs (67.39±49.90ng/mL) and serum (73.48±34.63ng/mL). The largest and smallest length of the ovaries was 26.0±3.0 and 19.0mm ±2.0mm, respectively. The number of SFs (70.86±25.76) was greater (P<0.01) than LFs (6.54±5.26). The study concluded that LFs present greater levels of IGF-I when compared with SFs and blood, which is related to increased activity of the LFs and its differentiation to ovulation. In addition, ovaries of pre-pubertal gilts have a higher number of SFs compared to LFs. Therefore, our study demonstrated unique data regarding the physiological concentration of free IGF-I in ovarian follicles, that can be used in future research to evaluate the addition of this hormone in the in vitro production media of porcine embryos with the goal to improve the technique efficiency.

Field experiments were conducted in 2010 and 2011 at two locations in Michigan to determine the effects of nitrogen and weed removal on glyphosate-resistant sugarbeet yield and quality. Nitrogen rates were 0, 67, 100, 134, and 67 : 67 kg N ha−1, and weeds were removed when they were < 2, 8, 15, and 30 cm tall. At the beginning of the growing season, weeds responded to N sooner than sugarbeet. Nitrogen assimilation by weeds was three times greater than sugarbeet at 0, 67, 100, and 134 kg N ha−1 and four times greater than sugarbeet with the split application of N (67 : 67 kg N ha−1) averaged over the weed removal timings. Higher N rates increased N sufficiency index values and sugarbeet canopy closure; weeds 30 cm tall had lower N sufficiency index values and a smaller sugarbeet canopy. The effect of N on root yields varied, but the highest N rates (134 kg N ha−1 or 67 : 67 kg N ha−1) were among the highest sugarbeet yields at all locations. Highest yields were achieved when weeds were controlled before reaching 2 cm tall at three of the four site-years. Delaying weed control until weeds were 8 or 15 cm tall reduced yield by 15%, whereas 30-cm-tall weeds reduced yield up to 21%. Recoverable white sucrose ha−1 (RWSH) also was reduced by 8 to 16% if weeds were 8 cm tall. These results indicate that weeds are highly competitive with sugarbeet and can assimilate large quantities of N early in the growing season, especially at larger growth stages. However, it appears that sugarbeets were able to scavenge sufficient N at the N rates used in this study to overcome N removal effects from larger weeds, resulting in no interaction between N rate and weed removal timing for sugarbeet root yield, quality, or RWSH.

Small burnet is a hardy, relatively long-lived evergreen forb with the potential to improve grazing lands, particularly to extend grazing into late fall and winter. Small burnet was evaluated for tolerance to spring and fall POST applications of aminopyralid, bromoxynil, clethodim, clopyralid, dicamba, dimethenamid-P, imazamox, metribuzin, pendimethalin, quinclorac, and 2,4-DB. Injury, seed yield, seed viability, and dry matter yield (DMY) were measured in the spring following application. Injury was observed in response to all spring and fall herbicide applications. Injury from aminopyralid was the highest for both spring and fall applications at 24 and 79%, respectively. Fall application of imazamox and dicamba resulted in 57 and 31% injury, respectively. Spring-applied aminopyralid and 2,4-DB both reduced DMY by 16%, whereas fall applications of imazamox, dicamba, and aminopyralid reduced DMY by 36, 12, and 67%, respectively. Fall applications of imazamox and aminopyralid reduced seed yield by 33 and 65%, respectively. Fall-applied aminopyralid reduced seed germination by 43%. None of the spring-applied herbicides affected seed yield or seed germination. Small burnet is severely injured by aminopyralid and to a lesser degree by imazamox and dicamba. Bromoxynil, clethodim, clopyralid, dimethenamid-P, metribuzin, pendimethalin, and quinclorac did not affect small burnet DMY, seed yield, or germination the year after application.

A commercial intrarow rotating cultivator was tested for weed removal and impact on hand-weeding times in bok choy, celery, lettuce, and radicchio. The rotating cultivator was tested as an automated crop thinner and weeder in direct-seeded bok choy and lettuce as an alternative to hand-thinning and -weeding. The rotating cultivator utilized machine-vision guidance to align a rotating disk with the crop plant to be saved and to remove weeds and undesired crop plants. The rotating cultivator was compared to a standard interrow cultivator, which could not remove weeds from the plant line. Main plots were cultivator type, rotating, or standard, and subplots were herbicides: pronamide for lettuce or prometryn for celery. Weed densities, hand-weeding times, crop stand, and yields were monitored. Economic analysis was performed on a subset of the data. The intrarow rotating cultivator was generally more effective than the standard interrow cultivator for reducing weed densities and hand-weeding times. However, the rotating cultivator reduced seeded lettuce stands by 22 to 28% when compared to hand-thinning and standard cultivation, resulting in lower yields and net returns. In transplanted celery, lettuce, and radicchio, the rotating cultivator removed more weeds than the standard cultivator, and reduced stands by just 6 to 9% when compared to the standard cultivator. In transplanted lettuce, the rotating cultivator was more precise and did less damage to the crop. Because transplanted crops were larger than the weeds, they were more easily differentiated using this technology. Net returns were therefore similar between the two cultivators. What is needed for celery and leafy vegetables is an effective intrarow weed removal system that reduces or eliminates the need for hand-weeding yet does not reduce yields. The rotating cultivator was developed for transplanted crops, where it performs adequately, but it cannot be recommended in the seeded crops evaluated.

Cantaloupe and watermelon growers in the southeastern United States use a system of hybrid transplants grown on narrow low-density polyethylene (LDPE) mulch-covered seedbeds with overhead irrigation and use the mulch cover for only one crop. LDPE mulches are costly to remove from the field and dispose. Biodegradable mulches that eliminate removal and disposal costs would be of significant benefit, provided that weeds are adequately suppressed. Cotton gin trash is a biodegradable waste product, composed of fiber fragments and seed pieces. Using a proprietary process, cotton gin trash can be chopped, pressed, and heated into a loose mat and stored on a continuous roll. Preliminary studies were conducted in 2010 and 2011 to determine if rolled cotton fiber mulch made from gin trash could be applied as a seedbed cover using conventional application equipment and adequately suppress weeds. Mulching materials (rolls 91 cm wide) were applied with a mulch layer that produced a finished seedbed 40 cm wide. ‘Athena' cantaloupe and ‘Crimson Sweet' watermelon were transplanted using a waterwheel transplanter. Mulching materials included rolled cotton fiber mulch sprayed with boiled linseed oil after mulch application, rolled cotton fiber mulch sprayed with black latex paint, black LDPE, and bare ground. Herbicide treatments included ethalfluralin, halosulfuron, and glyphosate applied as directed spray and nontreated with herbicides. Rolled cotton fiber mulch was easily applied with a conventional mulch layer with no modification and minimal adjustment, producing no tears or holes. Biodegradable cotton fiber mulch treated with boiled linseed oil or black latex paint suppressed weeds equally well as LDPE and all were better than bare-ground plots. Herbicides improved control of all weeds over the nontreated control and this effect was independent of weed suppression provided by seedbed mulches. Cantaloupe and watermelon yields were not affected by seedbed mulches, but were increased by weed control provided by herbicides.

Sedges are problematic weeds that reduce quality of turfgrass sod, and herbicides may be needed for control prior to harvesting. The objective of this research was to evaluate application timing of halosulfuron and sulfentrazone on sod quality, tensile strength, and postharvest rooting of four warm-season turfgrasses. Bermudagrass injury from herbicides was minimal (< 10%), but injury to centipedegrass, St. Augustinegrass, and zoysiagrass was detected before harvesting and generally increased with sulfentrazone rate from 0.21 to 0.84 kg ai ha−1. Sod tensile strength was not reduced from the nontreated for bermudagrass and centipedegrass treated with herbicides, but tensile strength was reduced 15 and 22% following herbicide applications 1 wk before harvesting (WBH) St. Augustinegrass and zoysiagrass, respectively. Sulfentrazone at 0.84 kg ha−1reduced zoysiagrass tensile strength 20% from the nontreated, but other treatments did not reduce measurements. Turfgrass injury from halosulfuron was negligible on all species, and treatments did not affect sod tensile strength of the four species. Treatments did not affect root mass of any species at 4 wk after sod transplanting. Sod quality after transplanting was reduced from the nontreated on several dates for centipedegrass and St. Augustinegrass when treated with sulfentrazone 1 and 2 WBH, and zoysiagrass quality was reduced from treatments 4 WBH. Bermudagrass quality after transplanting was not reduced from the nontreated by any herbicides. Results suggest sod harvesting should be delayed 1, > 2, > 2, and ≥ 4 weeks after sulfentrazone applications at labeled rates for bermudagrass, centipedegrass, St. Augustinegrass, and zoysiagrass, respectively. Sod harvesting should be delayed 1, 2, ≥ 4, and 2 wk after halosulfuron treatments at 0.07 kg ai ha−1for bermudagrass, centipedegrass, St. Augustinegrass, and zoysiagrass, respectively.
