HIV Diagnosis Time Differentiates ART Initiation: Implications from a Prospective Cohort Study in China

Background: We estimated the predictive effects of ART-related perceptions on the actual ART uptake behavior among ART naïve PLWH stratified by different time of HIV diagnosis under the new strategy. Methods: A prospective cohort study was conducted among ART naïve PLWH in Guangzhou, China from June 2016 to June 2017. Cox regression model was used to evaluate the predictive effects of ART-related perceptions on ART initiation among PLWH stratified by different timepoint of HIV diagnosis (i.e., before or after the update of the new treatment policy). Results: Among 411 participants, 150 and 261 were diagnosed before (pre-scaleup group) and after (post-scaleup group) the implementation of the new strategy, respectively. The ART initiation rate in the post-scaleup group (88.9%) was higher than that in the pre-scaleup group (73.3%) (p<0.001). A significant difference of mean score was detected in each HBM construct between pre- and post- scaleup groups (p<0.05). After adjusting for significant background variables, among all participants, only the self-efficacy (adjusted HR (HRa) =1.23, 95% C.I. : 1.06 to 1.43, p=0.006), has a predictive effect on ART initiation; in pre-scaleup group, all constructs of HBM-related ART perceptions were predictors of ART initiation (HRa=0.71 to 1.83, p<0.05), while in post-scaleup group, no significant difference was found in each construct (p>0.05). Conclusions: The ART initiation rate was high particularly among participants who diagnosed after the new treatment strategy. The important role of the time of HIV diagnosis on ART initiation identified in this study suggested that future implementation interventions may consider to modify the ART-related perceptions for HIV patients who diagnosed before the implementation of the new ART strategy, while expand the accessibility of ART service for those who diagnosed after the implementation of the new strategy.

Objective: To isolate and identify various bacterial pathogens in positive ear swab cultures of CSOM cases and to determine the antibiotic sensitivity pattern of different bacterial species identified. Study design: Prospective study Setting: J. L. N. Hospital & Research Centre, Bhilai (C.G). Materials and Method: The study was done on the population of Bhilai and surrounding region. A sample size of 120 cases attending the ENT OPD with the diagnosis of Chronic Suppurative Otitis Media and active ear discharge were included in the study. Detailed history, general physical examination, local systemic examination was done along with aural swab for Gram’s staining and aerobic bacterial culture and drug sensitivity . The data were then compared with the relevant & available literature. Results: Most of the patients were in the age group of 11-20 years (38.33%), followed by 21-30 years age group (31.67%). More males (60%) were affected by the disease than females (40%). Unilateral (59.16%) infection was more common than bilateral (40.83%). Incidence of monobacterial (90%) etiology was more common than polymicrobial (9.1%). Staphylococcus aureus 67 (51.53%) was the most commonly isolated bacteria followed by the Pseudomonas 26 (20%). Antibiogram showed the most effective drugs in the present study are clindamycin, cotrimoxazole, ciprofloxacin, amikacin, chloramphenicol and ceftazidime Conclusion: Staphylococcus aureus is the most common pathogen isolated, followed by Pseudomonas. Clindamycin was the most effective antibiotic followed by cotrimoxazole, ciprofloxacin, amikacin, chloramphenicol and ceftazidime. Antibiotic sensitivity of the organisms varies according to geographical area and local practice regarding the choice of antibiotics. A continuous and periodic evaluation of microbiological pattern and their antibiotic sensitivity pattern in local area is helpful in prescribing empirical antibiotics for successful treatment of otitis media and thus minimi
Synthesis, synchrotron diffraction study and twinning in Na2Ca4Mg2Si4O15 – a heteropolyhedral framework compound

Abstract The formation of polycrystalline Na2Ca4Mg2Si4O15 from solid state reactions has been studied between 800 and 1050°C. Single crystals of the compound have been grown in a closed platinum capsule by slow cooling in the temperature range between 1300 and 1000°C. Basic crystallographic data are as follows: monoclinic symmetry, space group P12/c1, a=7.1717(3) Å, b=5.3512(2) Å, c=16.4789(7) Å, β=90.911(4)°, V=632.33(4) Å3, Z=2. A conspicuous feature of the crystals is an intensive lamellar non-merohedral twinning clearly observable already under a petrographic microscope. The diffraction pattern can be explained as a superposition of two reciprocal lattices with a two-fold axis parallel to [001] being the twin element. Using synchrotron radiation it was possible to solve the crystal structure of Na2Ca4Mg2Si4O15 from a twinned data set. Least-squares refinements resulted in a residual of R(|F|)=0.031 for 2899 observed reflections with I>2σ(I) and 127 parameters. The crystal structure contains both [Si2O7]-dimers and insular [SiO4]-moieties. Tetrahedra and [MgO6]-octahedra form a three-dimensional framework whose topological characteristics have been studied. The remaining calcium and sodium cations are distributed among four crystallographically independent positions located in voids of the network. On a microscopic scale the twinning observed in the diffraction experiments could be explained by the existence of a 21-screw axis parallel to [001] in (¼, 0, z) mapping both domains onto each other. A comparison with related compounds having an A+2B2+6Si4O15 stoichiometry is presented. More than 25 years after its first observation in refractories our investigation clarifies the crystal structure of a silicate that is of relevance for both Materials science and high pressure research.
Knowing the Prognosis of Prostate Cancer from the Initial Core Needle Biopsy Report

It has long been thought that the pathologic staging of prostate cancer and its prognosis can only be determined after radical prostatectomy; however, there is evidence on the possibility of establishing this prognosis from the initial study of the core needle biopsy, which would allow the doctor and the patient to prepare to assume the evolution of the disease from the moment of the initial diagnosis, allowing a greater period to take measures that facilitate coping with the disease.
Imaging analysis of 13 rare cases of renal collecting (Bellini) duct carcinoma patients in northen China.

Background: Collective duct carcinoma (CDC) is a highly malignant kidney tumor which is rare in clinical. We report our 12-year experience of Collecting (Bellini) duct carcinoma (CDC) and retrospectively analyzed patients and tumour characteristics, clinical manifestations, different imaging characteristics including CT, MRI and PET/CT. Methods: From January 2007 to December 2019, we retrospectively examined all renal tumors and identifed 13 cases of CDC from 3 medical centers in the northern China. All 13 patients underwent CT scan, 8 of whom underwent dynamic enhanced CT scan, 2 underwent PET/CT scan and 1 underwent MRCP examination. The lesions were divided into nephritis type and mass type according to the morphology of the tumors.Results: The study group included 10 men and 3 women, with an average age of 64.23±10.74 years old. Of these 13 patients, the main clinical manifestations include gross hematuria, flank pain or waist discomfort. The mean tumour size was 8.48 ± 2.48 cm. In this group of cases, 6 (46.2%) cases are cortical-medullary involved type, 7 (53.8%) cases are cortex-medullary-pelvis involved type. 11 (84.6%) cases were nephritis type and 2 (15.4%) cases were mass type. The lesions appeared solid or complex solid and cystic on CT and MRI. The parenchymal part of 13 CDC tumors showed isodensity or slightly higher density on unenhanced CT scan. the parenchymal part of 13 CDC tumors showed isodensity or slightly higher density on unenhanced CT scan. Two patients with PET/CT showed increased radioactivity intake. Evidence of intra-abdominal metastatic disease was present on CT in 9 ( 69.2% ) cases. The incidence of metastasis reached 69%. Conclusions: The Collecting (Bellini) duct carcinoma has its certain imaging characteristics which were different from the other renal cell carcinoma. A renal tumor should be considered as CDC when it locates in the junction zone of the renal cortex and medulla, with unclear border, slight enhancement and metastases in early stage. PET/CT can greatly enrich the key information of diagnosis, surgery and treatment options, which provide significant help to the clinic.
EFFECTS OF LEADERS-FOLLOWERS EXCHANGE (LMX) ON ORGANIZATIONAL COMMITMENT AND TURNOVER INTENT IN HOSPITALITY AND PUBLIC SERVICES

Based on the specifics of the selected service sectors hospitality and public, it is clear that the role of leaders significantly varies. Antecedents for achieving organizational and individual goals include a quality relationship between leaders and followers (supervisors and subordinates), making it possible for an organization to be functional and successful and employees satisfied at work. Although the concept of leadership is as old as human civilization, numerous multi-annual researches and thousands of studies have not yielded with a clear idea of what the leadership is and how best the organizational and individual goals could be achieved. This paper focuses on the effects of the quality of leaders followers exchange to organizational commitment and turnover intent (intention to leave).
Regenerative Endodontic Treatment in Teeth with Internal Root Resorption: An Insight Over the Available Literature

Internal root resorption (IRR) is a resorptive defect of the root's internal aspect, and its pathogenesis occurs because of the activity of odontoclasts. If left untreated, IRR will eventually cause necrosis of the pulp tissue apical to the resorptive lesion, leading to periapical pathologies and resistance failure of the tooth. Treatment of this kind of pathology encompasses many options ranging from conventional root canal treatment to endodontic surgery. The most recent innovation for the treatment of IRR is revascularization. The present review aims to discuss revascularization as a treatment option for IRR. An extensive search for recent available data regarding this kind of treatment and potential suggestions for the future have been made. Revascularization of teeth with IRR has promising results and should be considered a choice for treating IIR cases as an alternative to conventional root canal treatment.

DETERMINATION OF PHYSICAL AND ENGINEERING PROPERTIES OF TIGER NUT (Cyperus esculentus) RELEVANT TO ITS MECHANIZATION

The physical and engineering properties of fresh and dried tiger nut (Cyperus esculentus) were determined at moisture content of 41.20% and 16.40% on wet basis respectively. The mean values for the three principal axes (length, width and thickness) were 9.52mm, 8.16mm, and 8.16mm for fresh tiger nut and 9.14mm, 7.72mm and 8.03mm for dried tiger nut respectively, showing a decrease with decrease in moisture content and was significantly different at p˂0.05. The mean values of the bulk density, true density and porosity of both fresh and dried tiger nut were 0.59g/cm, 0.97g/cm, 40.61 and 0.58g/cm, 0.94g/cm, 40.35 respectively and were not significantly different at p˂0.05. The mean angle of repose and coefficient of static friction over formica, stainless steel, glass and plywood surfaces of fresh tiger nut were 50.11, 2.73, 2.45, 2.22 and 1.77 while that of dried tiger nut were 48.23, 2.41, 2.03, 2.11 and 2.00 respectively. The mean rupture force increased with compression force of 90.08N on the major axis to 116.88N for fresh tiger nut and from 120.55N to 161.10N for dried tiger nut and were significantly different at p˂0.05. These properties determined are necessary in the design and fabrication of hoppers, conveyor equipment and the force tiger nut can withstand before it is ruptured.
Expression of OsFRDL1, a MATE gene family member, indicates its involvement in aluminum response in rice

In soils under acidic conditions, Aluminum (Al) is solubilized to its ionic form, which is toxic to plants. Al rapidly inhibits root elongation, water and nutrient uptake, resulting in crop yield reduction. Members of the MATE family are responsible for citrate transport and Al detoxification in different species. In rice, the OsFRDL1 gene (MATE family) is homologous to the HvAACT1 and SbMATE, which are involved in Al tolerance in barley and sorghum, respectively. Silencing OsFRDL1 showed that it is not involved in Al tolerance in rice. However, the OsFRDL1 expression was not accessed in rice genotypes contrasting for Al tolerance. Thus, in this study, four Brazilian rice genotypes were evaluated in response to Al treatment in different time of exposition and OsFRDL1 expression was analyzed. The analyzed cultivars displayed different responses to Al dose x time. Al affected root growth in all analyzed genotypes, however, a minor negative effect that only occurred after 72 and 48 hours of exposure was detected in Farroupilha and BRS Curinga cultivars, respectively. In contrast, BR-IRGA 410 and IAS 12-9 showed a negative effect in root growth from the first hours of exposure to Al. Two cultivars differing in Al tolerance were used for gene expression analysis. The expression of OsFRDL1 was highly increased in Al-tolerant cultivar Farroupilha than in the Al-sensitive cultivar BR IRGA 410. This results indicates that OsFRDL1 is regulated by Al. This finding suggests that OsFRDL1 is involved in Al stress response, however seems to be insufficient in controlling Al tolerance.
Density Separation of Imbibed and Primed Vegetable Seeds

The objective of this study was to determine the relationship between seed density and seed quality of vegetable seeds hydrated by imbibing or priming procedures. Species studied were: lettuce (Lactuca sativa L.), tomato (Lycopersicon esculentum Mill.), onion (Allium cepa L.), cabbage (Brassica oleracea var. capitata L.), and carrot (Daucus carota L.). Seeds of each crop were soaked in either aerated distilled water at 25C (imbibed seeds) or polyethylene glycol (PEG) 8000 at 15C (primed seeds). After soaking, seeds were separated into density classes with a float-sink procedure using aqueous solutions of Maltrin 600 (Maltrin 500 for lettuce) with 0.02 g·cm−3 density increments. Significant (P > 0.01) positive relationships were determined between seed density classes and germination percentages for lettuce, tomato, and onion seeds, whether separated after imbibition (R2 = 0.93, 0.83, and 0.66, respectively) or after priming (R2 = 0.95, 0.94, and 0.91, respectively). High-density classes of hydrated lettuce, tomato, and onion seeds in either the imbibed or primed treatment usually exhibited faster and more uniform rates of radicle emergence and, after 6 days, had longer hypocotyls (cotyledon for onions) than low-density classes. The significant quality differences exhibited among the density classes of lettuce, tomato, and onion seeds after priming will enable seedlots of these species to be upgraded by discarding the low-density, poor-quality seeds.
Bis(imino)pyridines Incorporating Doubly Fused Eight-Membered Rings as Conformationally Flexible Supports for Cobalt Ethylene Polymerization Catalysts

Five distinct α,α′-bis(arylimino)-2,3:5,6-bis(hexamethylene)pyridine-cobalt(II) chloride complexes, [2,3:5,6-{C5H10C(NAr)}2C5HN]CoCl2 (Ar = 2,6-Me2C6H3, Co1; 2,6-Et2C6H3, Co2; 2,6-i-Pr2C6H3, Co3; 2,4,6-Me3C6H2, Co4; 2,6-Et2-4-MeC6H2, Co5), have been synthesized by one-pot template reaction of α,α′-dioxo-2,3:5,6-bis(hexamethylene)pyridine with the corresponding aniline and cobalt(II) chloride in acetic acid. The molecular structures of Co2 and Co3 reveal distorted square pyramidal geometries with two conformationally flexible eight-membered rings, a feature of the ligand manifold. On activation with either methylaluminoxane (MAO) or modified MAO (MMAO), all five complexes displayed high catalytic activities for ethylene polymerization (up to 3.62 × 106 g PE mol–1 (Co) h–1) generating strictly linear polyethylenes with the activity decreasing in the orders: Co4 > Co5 > Co1 > Co2 > Co3 (MAO) and Co1 > Co4 > Co2 > Co5 > Co3 (MMAO). Moreover, the nature of the aluminoxane cocatalyst employed had a marked effec.

Study on sustainable livelihoods of fishers from Chalan beel, Bangladesh

An assessment was carried out to observe the impacts of fish sanctuary on the livelihoods from fishers of Ruhul beel and Bamonji beel under Chalan beel in Pabna district of Bangladesh. Data were collected from selected sanctuary sites with prepared and pretested questionnaire and analyzed through statistical tests like ANOVA (Analysis of Variance), regression, correlation, Chi-square were used to identify the relationships between variables and significant differences/association among them. From physical capital point of view, it was found that 91.3% of fishermen’s houses were katcha, 6.52% were semi-pacca, and only 2.17% were pucca in case of Ruhul beel and in case of Bamonji beel 90.54% of fishermen’s houses were katcha, 8.11% were semi-pacca, and only 1.35% were pacca. There was no significant variation (ANOVA; P>0.05, Chi Square test; non-significant at 0.05 level) among the residences by well-being. From human capital, average age of the household heads (HHH) was 37.95(±) 1.354 for Ruhul beel respectively, whereas for Bamonji beel the average age were 38.05(±) 1.064. The medium aged group fishermen were dominant in Ruhul beel than Bamonji beel. There were no significant difference (P>0.05) found between the age groups by well-being. From income capital it was observed highest part of income were come from fishing contributing 64.89% (653.72±128.82 US$), 43.58% (431.89±74.66 US$) for Ruhul beel and Bamonji beel respectively. As per as natural and social capital, average used land holding was 0.274±0.136 ranging 0.065 ha to 0.534 ha for Ruhul beel and 0.228±0.305 ha ranging 0.040 to 0.267 ha for Bamonji beel. The average land holdings did not vary significantly (P>0.05) between the sites.

Production Potential of forage Maize ( Zea mays L.) - Cowpea ( Vigna unguiculata L.) Intercropping System as Influenced by Row Ratios

A field experiment was conducted during Kharif season of 2010 at Main Forage Research Station, Anand Agricultural University, Anand to study the production potential of forage maize-cowpea intercropping system as influenced by row rations. Intercropping of maize and cowpea in 2:1 row ratio recorded significantly higher total (maize + cowpea) green forage (422.92 q /ha) and dry matter yield (98.92 q/ha). Cowpea as an intercrop helped to enhance crude protein content and total crude protein yield of intercropping system. The maximum (5.44 %) crude protein content of maize was achieved with the row ratio of 2 : 1 and this treatment also recorded higher total crude protein yield (7.73 q/ha).
