Mechanical damage to green and red lentil seeds

Abstract In this research, the breakage susceptibility of two classes of lentil (green and red) was evaluated as affected by impact energy and seed moisture content. The experiments were conducted at impact energies of 0.1, 0.2 and 0.3 J, and moisture contents of 10, 12.5, 15, 17.5, 20 and 25% (wet basis). Results showed that red lentil seeds had more breakage than green seeds and the difference in breakage percentage between green and red lentil seeds was significant at 0.01% level according to analysis of variance (p < .01). Percentage breakage of both green and red lentil seeds increased as the energy of impact increased. With increasing the seed moisture content of the both green and red lentils, the breakage percentage of seeds decreased. The average values of seeds breakage green and red lentil seeds varied from 100 to 67.7% and from 100 to 93.1%, respectively, as the seeds moisture content increased from 10 to 25%. The optimum seed moisture at which minimum damage was observed was 17.5% for green lentil and 15% for red lentil. Mathematical relationships composed of lentil seeds moisture content and energy of impact were developed for accurate description of the breakage percentage of green and red lentil seeds under impact loading.
Deceased-Donor Renal Transplantation in the Geriatric Population Demonstrates Equal Graft Survival Compared With Younger Recipients

Background. Renal transplantation (RTx) in the geriatric population (age >65 years) accounts for 14% of all RTx performed nationally in 2007. Methods. We reviewed 3297 RTx recipients from our database over a 15-year period to evaluate recipient and donor age, date of transplant and graft loss, cause of graft loss, and cold ischemic time in the geriatric population. Results. Since 1991, we have performed 468 living donor RTx (LDRTx) and deceased donor RTx (DDRTx) in patients more than 65 years: 280 (65–69 years), 128 (70–74 years), and 60 (>75 years). Geriatric recipients of DDRTx demonstrated 83.0%, 74.1%, and 64.1% uncensored graft survival at 1, 3, and 5 years, respectively. Interestingly, these rates were similar compared with DDRTx in adults (18–64 years, P=0.49). Geriatric recipients of LDRTx demonstrated 1-year, 3-year, and 5-year graft survival rates of 94.3%, 88.8%, and 72.3%, respectively. Although better than geriatric DDRTx recipients, these results were not equal to the success of adult LDRTx recipients, potentially because of poorer graft survival in LDRTx recipients more than 75 years (P=0.004). Death-censored graft survivals were similar between adult and geriatric recipients of LDRTx (P=0.28). Graft loss secondary to death was twice as great in geriatric versus adult recipients (P<0.01). Conclusions. DDRTx geriatric recipients of each group showed similar uncensored graft survivals to adult DDRTx recipients. LDRTx had better outcomes than DDRTx in geriatric recipients. Death-censored outcomes were similar between adult and geriatric LDRTx recipients. These data support the equivalent outcomes of RTx in appropriately selected geriatric recipients.
Baboon responses to graded bark variants

We studied chacma baboons’, Papio cynocephalus ursinus, responses to conspecific ‘barks’ in a free-ranging population in the Okavango Delta of Botswana. These barks grade from tonal, harmonically rich calls to calls having a noisier, harsher structure. Tonal or clear barks are typically given when the signaller is at risk of losing contact with the group or when a mother and infant have become separated (‘contact barks’). The harsher variants are given in response to predators (‘alarm barks’). In both contexts, however, we also observed acoustically intermediate forms. Using the habituation–recovery method we tested whether baboons discriminated between (1) clear contact barks versus harsh alarm barks, and (2) clear contact barks versus intermediate alarm barks. Calls were selected according to the results of a discriminant function analysis conducted on a suite of acoustic parameters. In these experiments, animals showed a significant recovery of response only after playback of the harsh alarm call. We performed another set of experiments using single exemplars of clear and intermediate contact barks, or intermediate and harsh alarm barks. Animals responded only to the playback of a harsh alarm bark. Apparently, only this harsh variant was placed in a category that warranted a response. We hypothesize that baboons’ responses were to a large degree influenced by their assessment of context.  2001 The Association for the Study of Animal Behaviour
Huddle-Coaching: A Dynamic Intervention for Trainees and Staff to Support Team-Based Care

Many outpatient clinics where health professionals train will transition to a team-based medical home model over the next several years. Therefore, training programs need innovative approaches to prepare and incorporate trainees into team-based delivery systems. To address this need, educators at the San Francisco Veterans Affairs (VA) Medical Center included trainees in preclinic team “huddles,” or briefing meetings to facilitate care coordination, and developed an interprofessional huddle-coaching program for nurse practitioner students and internal medicine residents who function as primary providers for patient panels in VA outpatient primary care clinics. The program aimed to support trainees’ partnerships with staff and full participation in the VA’s Patient Aligned Care Teams. The huddle-coaching program focuses on structuring the huddle process via scheduling, checklists, and designated huddle coaches; building relationships among team members through team-building activities; and teaching core skills to support collaborative practice. A multifaceted evaluation of the program showed positive results. Participants rated training sessions and team-building activities favorably. In interviews, trainees valued their team members and identified improvements in efficiency and quality of patient care as a result of the team-based approach. Huddle checklists and scores on the Team Development Measure indicated progress in team processes and relationships as the year progressed. These findings suggest that the huddle-coaching program was a worthwhile investment in trainee development that also supported the clinic’s larger mission to deliver team-based, patient-aligned care. As more training sites shift to team-based care, the huddle-coaching program offers a strategy for successfully incorporating trainees.
Mechanical transmission of lumpy skin disease virus by Aedes aegypti (Diptera: Culicidae)

Aedes aegypti female mosquitoes are capable of the mechanical transmission of lumpy skin disease virus (LSDV) from infected to susceptible cattle. Mosquitoes that had fed upon lesions of LSDV-infected cattle were able to transmit virus to susceptible cattle over a period of 2–6 days post-infective feeding. Virus was isolated from the recipient animals in 5 out of 7 cases. The clinical disease recorded in the animals exposed to infected mosquitoes was generally of a mild nature, with only one case being moderate. LSDV has long been suspected to be insect transmitted, but these findings are the first to demonstrate this unequivocally, and they suggest that mosquito species are competent vectors.
Channel Characterization for Indoor Power-Line Networks

Power-line networks are promising mediums by which broadband services can be offered, such as Internet services, voice over Internet protocol, digital entertainment, etc. In this paper, an analysis of delay spread, coherence bandwidth, channel capacity, and averaged delay in the frequency bands up to 100 MHz for typical indoor power-line networks are studied. Earlier studies for indoor power-line networks considered frequencies up to 30 MHz only and earlier works have shown that at these frequency bands, the data rates are generally low and are inefficient for digital entertainment in comparison with wireless local-area networks standards, such as IEEE 802.11 n. In this paper, it is shown that at 100 MHz, the average channel capacity for typical indoor power-line networks can be up to 2 Gb/s and it is found that by increasing the number of branches in the link between transmitting and receiving ends, the average channel capacity decreases from 2 Gb/s to 1 Gb/s (when the number of branches was increased by four times for a power spectral density of -60 dBm/Hz). At the same time, the coherence bandwidth decreased from 209.45 kHz to 137.41 kHz, which is much better than the coherence bandwidths corresponding to 30-MHz systems. It is therefore recommended to operate the indoor power-line networks at 100-MHz bandwidths for a wide variety of broadband services.
Within-Person Relationships Among Daily Self-Esteem, Need Satisfaction, and Authenticity

This study examined the within-person relationships among daily self-esteem, felt authenticity (i.e., the operation of one's “true self”), and satisfaction of psychological needs for autonomy, competence, and relatedness. We also included measures of affect to control for the variance these constructs might share with affect. Over a 2-week period, 116 participants responded daily to measures of these variables. Multilevel random-coefficients modeling revealed that authenticity, autonomy, competence, and relatedness were all positively and significantly related to daily reports of self-esteem, even when we controlled for the contributions of pleasant and unpleasant affect. We discuss the roles of authenticity and psychological needs in daily feelings of self-worth.
A System for Nuclear Fuel Inspection Based on Ultrasonic Pulse-Echo Technique

Nuclear Pressurized Water Reactor (PWR) technology has been widely used for electric energy generation. The follow-up of the plant operation has pointed out the most important items to optimize the safety and operational conditions. The identification of nuclear fuel failures is in this context. The adoption of this operational policy is due to recognition of the detrimental impact that fuel failures have on operating cost, plant availability, and radiation exposure. In this scenario, the defect detection in rods, before fuel reloading, has become an important issue. This paper describes a prototype of an ultrasonic pulse-echo system designed to inspect failed rods (with water inside) from PWR. This system combines development of hardware (ultrasonic transducer, mechanical scanner and pulser-receiver instrumentation) as well as of software (data acquisition control, signal processing and data classification). The ultrasonic system operates at center frequency of 25 MHz and failed rod detection is based on the envelope amplitude decay of successive echoes reverberating inside the clad wall. The echoes are classified by three different methods. Two of them (Linear Fisher Discriminant and Neural Network) have presented 93% of probability to identify failed rods, which is above the current accepted level of 90%. These results suggest that a combination of a reliable data acquisition system with powerful classification methods can improve the overall performance of the ultrasonic method for failed rod detection.
Assessment of pulmonary hypertension in the pediatric catheterization laboratory: Current insights from the magic registry

Objectives: To assess protocols, demographics, and hemodynamics in pediatric patients undergoing catheterization for pulmonary hypertension (PH). Background: Pediatric specific data is limited on PH. Methods: Review of the Mid‐Atlantic Group of Interventional Cardiology (MAGIC) collaboration PH registry dataset. Results: Between November 2003 and October 2008, seven institutions submitted data from 177 initial catheterizations in pediatric patients with suspected PH. Pulmonary arterial hypertension associated with congenital heart disease (APAH‐CHD) (n = 61, 34%) was more common than idiopathic PAH (IPAH) (n = 36, 20%). IPAH patients were older with higher mean pulmonary arterial pressures (mPAP) (P < 0.01). Oxygen lowered mPAP in patients with IPAH (P < 0.01) and associated PAH not related to congenital heart disease (APAH‐non CHD) (P < 0.01). A synergistic effect was seen with inhaled Nitric Oxide (iNO) (P < 0.01). Overall 9/30 (29%) patients with IPAH and 8/48 (16%) patients with APAH‐non CHD were reactive to vasodilator testing. Oxygen lowered pulmonary vascular resistance index (PVRI) in patients with APAH‐CHD (P < 0.01). There was no additive effect with iNO but a subset of patients required iNO to lower PVRI below 5 WU·m2. General anesthesia (GA) lowered systemic arterial pressure (P < 0.01) with no difference between GA and procedural sedation on mPAP or PVRI. Adverse events were rare (n = 7) with no procedural deaths. Conclusions: Pediatric patients with PH demonstrate a higher incidence of APAH‐CHD and neonatal specific disorders compared to adults. Pediatric PH patients may demonstrate baseline mPAP < 40 mm Hg but > 50% systemic illustrating the difficulty in applying adult criteria to children with PH. Catheterization in children with PH is relatively safe. © 2010 Wiley‐Liss, Inc.
On Definite and Nilpotent DR Tree Languages

The sets recognized by deterministic root-to-frontier tree recognizers, the DR tree languages, are determined by their path languages. A path language of a tree language T consists of the words describing the paths leading from the root of a tree in T to its leaves labelled with a given leaf symbol. The greatest congruence saturating the path languages yields the syntactic path monoid of T which is finite for a path closed T exactly in case T is a DR tree language. We introduce the concepts of definite and nilpotent DR tree languages and, by means of syntactic path semigroups, characterize them.
Pharmacodynamics of Moxifloxacin against Anaerobes Studied in an In Vitro Pharmacokinetic Model

ABSTRACT The antibacterial effects of moxifloxacin against Bacteroides fragilis, Clostridium perfringens, and gram-positive anaerobic cocci (GPAC) were studied in an in vitro pharmacokinetic model. Initially, a dose-ranging study with area under the concentration-time curve (AUC)/MIC ratios of 6.7 to 890 was used to investigate the effect of anaerobic conditions on the AUC/MIC antibacterial effect (ABE) relationship with Escherichia coli. The AUC/MIC ratios for 50% and 90% effects, using a log CFU drop at 24 h as the antibacterial effect measure, were 34 and 59, respectively, aerobic and 54 and 96, respectively, anaerobic. These values are not significantly different. Dose ranging at AUC/MIC ratios of 9 to 216 against the anaerobes indicated a differing AUC/MIC ABE pattern, and the AUC/MICs for 50% and 90% effects were lower: for B. fragilis, they were 10.5 and 25.7, respectively; for C. perfringens, they were 8.6 and 16.2; and for GPAC, they were 7.3 and 17.4. The maximum-effect log drops were as follows: for B. fragilis, −3.2 ± 0.2 logs; for C. perfringens, −3.7 ± 0.1 logs; and for GPAC, −2.5 ± 0.1 logs. Although the anaerobes were not eradicated, there was no emergence of resistance. Comparison of the ABE of moxifloxacin to that of ertapenem against B. fragilis indicated that moxifloxacin was superior at 24 h and 48 h. In contrast, ertapenem was superior to moxifloxacin against GPAC at 24 h and 48 h and against C. perfringens at 48 h. Both drugs performed equivalently against C. perfringens at 24 h. Monte Carlo simulations using human serum AUC data and an AUC/MIC anaerobe target of 7.5 suggests a >90% target achievement at MICs of <2 mg/liter. This divides the B. fragilis wild-type MIC distribution. The pharmacodynamic properties of moxifloxacin against anaerobes are different than those against aerobic species. The clinical implications of these differences need further exploration.
Capacity for substrate utilization in oxidative metabolism by neurons, astrocytes, and oligodendrocytes from developing brain in primary culture

Neuron, astrocyte, and oligodendrocyte cultures which were established from developing rat brain were examined for their utlization of glucose, ketone bodies, and free fatty acids by oxidative processes. 14CO2 production was measured in these cells from [1‐14C] or [6‐14C]glucose; [1‐14C] and [1‐14C], [6‐14C], or [6‐14C]palmitate; and [3‐14C]acetoacetate and D(‐)‐3‐hydroxy[3‐14C]butyrate. Pyruvate dehydrogenase (EC 1.2.4.1.) abd 3‐oxoacid‐CoA transferase (EC 2.8.3.5.) activites were found at high levels in each of the cell population. Astrocytes and oligodendrocytes produced much more 14CO2 from [1‐14C]glucose than from [6‐14C]glucose, indcating substantial hexose monophosphate shunt activity. This process was not as active in neurons. All three cell populations readily utilized the ketone bodies for oxidative metabolism at rates 7–9 times greater than they utilize glucose. Only astrocytes were able to utilize fatty acids for 14CO2 production, and the rate of utilization was greater than of the ketone bodies. We found that the metabolic patterns of thesse brain cells which were derived from the developing brain complement the nature of the diet of the duckling animal which is rich fat and low in carbohydrate. They readily utilized the ketone bodies or fatty acids and spared glucose for processes that metabolites of fat cannot fulfill.
Differential tumorigenicity between Epstein-Barr virus genome-positive and genome-negative cell lines with t(11;14)(q13;q32) derived from mantle cell lymphoma

Epstein-Barr virus (EBV) genome has been detected in several human lymphoproliferative diseases, but the oncogenic function of EBV is not fully understood. We previously established EBV-positive (SP-50B) and EBV-negative (SP-53) cell lines with the t(11;14)(q13;q32) chromosome abnormality from a single patient with mantle cell lymphoma. Monoclonal EBV DNA in a circular episomal form was demonstrated in the SP-50B cells by Southern blot hybridization with the EBV-terminal fragment probe. SP-50B cells were positive for not only EBV-encoded nuclear antigen-1 (EBNA1) but also latent membrane protein-1 and EBNA2. None of the EBV-encoded proteins was expressed in SP-53 cells. The isogenic EBV-infected and EBV-free cell lines of neoplastic clones made it possible to examine a tumorigenic role of EBV. Only EBV-positive SP-50B cells possessed malignant phenotypes, such as growth ability in low serum, colony formation in soft agarose, and tumorigenicity in nude mice. On the other hand, a lymphoblastoid B-cell line established by infecting the patient's normal B lymphocytes in vitro with exogenous EBV had no tumorigenicity. These results suggested that EBV infection, if it occurred in neoplastic lymphoma cells, could play a role in acquisition of malignant phenotypes.
Cytoplasmic antigen in hepatocytes of chimpanzees infected with non‐A, non‐B hepatitis virus or hepatitis delta virus: Relationship to interferon

We previously described a cytoplasmic antigen, detected by monoclonal antibodies, in hepatocytes of chimpanzees experimentally infected with the parenterally transmitted form of non‐A, non‐B hepatitis virus or with the hepatitis delta virus. The expression of this antigen appears to be a host‐specified response to infection with these two hepatitis viruses but not with hepatitis A virus, hepatitis B virus or enterically transmitted non‐A, non‐B hepatitis virus. To determine whether this antigen, found in parallel with the hepatocyte cytoplasmic structures described previously, is associated with interferon, as suggested by others, we studied by immunofluorescence liver biopsies from chimpanzees treated with an interferon inducer or exogenous interferon for the presence of the antigen. In two hepatitis B virus carrier chimpanzees and one normal chimpanzee treated with the interferon inducer polyinosinic‐poly‐ribocytidylic acid‐poly‐l‐lysine carboxymethylcellulose, the antigen became detectable in hepatocytes within 2 weeks of initiation of the treatment, remained detectable throughout the treatment and disappeared within 4 weeks after treatment was terminated. Electron microscopy revealed that the biopsies positive for the antigen exhibited the hepatocyte cytoplasmic changes; convoluted membranes and microtubular aggregates, identical to those described originally for chimpanzees infected with non‐A, non‐B hepatitis virus. The antigen was not detected in any of the biopsies from a control chimpanzee that received only the carboxymethylcellulose used to stabilize the interferon inducer. In addition, liver biopsies obtained from a hepatitis B virus carrier chimpanzee during treatment with exogenous human leukocyte interferon were found to be positive for the antigen as well. It is likely that expression of this antigen and induction of the hepatocyte cytoplasmic structures are a host response to interferon induced by non‐A, non‐B hepatitis virus and hepatitis delta virus infections.
A Specific Epitope of Protein Inhibitor of Activated STAT3 Is Responsible for the Induction of Apoptosis in Rat Transformed Mast Cells1

Protein inhibitor of activated STAT3 (PIAS3) functions in vivo as a key molecule in suppressing the transcriptional activity of both microphthalmia transcription factor (MITF) and STAT3, two transcription factors that play a major role in the development, phenotypic expression, and survival of mast cells and melanocytes. In the present study we have investigated the role played by PIAS3 in the regulation of cell cycle in mast cells and melanocytes. We have characterized the biological role of a 23-aa domain derived from PIAS3 that induces apoptosis in these cells by inhibiting the transcriptional activity of both MITF and STAT3. This PIAS3 inhibitor peptide could serve as the beginning of an in depth study for the development of peptide inhibitors for MITF and STAT3.
Leaf Nitrate Reductase, d-Ribulose-1,5-bisphosphate Carboxylase, and Root Nodule Development of Genetic Male-Sterile and Fertile Soybean Isolines.

The objectives of this study were to determine the effect of pod and seed development on leaf chlorophyll concentration, and on activities of leaf ribulose bisphosphate carboxylase, leaf nitrate reductase, and root nodule acetylene reduction in field-grown soybean (Glycine max [L.] Merr.). Two genetic male-sterile lines and their fertile counterparts (Williams and Clark 63) were compared in both 1978 and 1979. Two additional lines (Wells x Beeson and Wells x Corsoy) were compared in 1979.The expression of male-sterile character was nearly complete as very little outcrossing due to insect pollinators was observed. Male-sterile plants showed a delayed late season decline in leaf chlorophyll content and ribulose bisphosphate carboxylase activity when compared with fertile plants. A slight delay in the loss of in vivo leaf nitrate reductase activity was also observed for male-sterile plants. Root nodule fresh weight and acetylene reduction activity declined slightly more rapidly for fertile lines than for male-sterile lines in both years with differences significant on the last two to three sampling dates as leaf loss occurred in the control plants.Seed development was found to increase slightly, the rate of decline of metabolic activity in fertile lines compared with that of male-sterile lines. However, pod development was not an a priori requirement for leaf and root nodule senescence. Male-sterile plants also lost photosynthetic and nitrogen metabolic competence, but at a slower rate. These results support the concept that pod and seed development does not signal monocarpic senescence per se but rather affects the rate at which senescence occurs after flowering.
