Abstract
Okra is an important traditional vegetable crop grown for its tender fruits in various tropical and sub tropical parts of the world. Yellow Vein Mosaic Disease (YVMD) is the major biotic factor causing severe threat to the okra fruit yield and qualities. The present study was conducted to find out the inheritance of resistance against YVMD and to identify the disease linked molecular markers through bulk segregant analysis. For this, the F1, BC1F1 and BC1F2 generations were derived from a cross between Abelmoschus manihot (PAUAcc-1) as resistant male parent and A. esculentus cv. Punjab Padmini as susceptible female parent. The whole set of populations (F1, BC1F1 and BC1F2) along with parents were subjected to artificial as well as filed screening against YVMD. Chi-square test for goodness to fit revealed that resistance against YVMD is controlled by two recessive genes. The allele of at least one gene in homozygous state mask the effect of other gene and produce a resistant phenotype. The very low polymorphism (31.5%) was detected between the parents by using SSR primers. Out of 200 SSR primers, the four primers i.e. Okra 032, Okra 049, Okra 129 and Okra 270 were found to be linked to YVMD through bulk segregant analysis. The identified SSR primers to YVMD could be further used in okra improvement for YVMD resistance.

Abstract
Celery is an important nutritionally rich crop in the family Apiaceae. It is cultivated worldwide for food as well as for use in pharmaceutics. It is an excellent source of minerals, vitamins, and phytochemicals. Identification of superior genotypes with improved nutritional content is the requirement to develop cultivars for commercial cultivation. For mineral analysis of celery, an experiment was carried out taking 20 diverse genotypes. These genotypes were analysed for macro- and micronutrients which include nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), and sodium (Na). The study revealed high content of K (20.3-26.1 mg/g dry weight (DW)) and Zn (0.09-0.14 mg/g DW) in leaves while the stalks were rich in Ca (41.5-51.3 mg/g DW) and Na (5.2-8.0 mg/g DW). High contents of P (5.2-6.8 mg/g DW), Fe (0.41-0.56 mg/g DW), Cu (0.015-0.026 mg/g DW), and Mn (0.020-0.029 mg/g DW) were observed in seeds. Based on the mineral content, three genotypes, viz., PAU2, PAU4, and PAU7, were found to be superior in terms of mineral composition in leaves, stalks, and seeds. Cluster analysis divided the genotypes into two major groups. These genotypes can be used in crosses as they showed great potential for use in biofortification. This study opens newer avenues for future research, encouraging researchers to enhance the product quality and production efficiency of the leaves, stalks, and seeds valuable for human consumption.

Abstract
Celery (Apium graveolens L.), a medicinal crop, occupies a significant position in the human diet possessing several essential macro- and microelements. For proper proximate analysis, an experiment was executed by taking 20 celery genotypes. The genotypes were analyzed for macro- and microminerals which include nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), sodium (Na), sulfur (S), zinc (Zn), iron (Fe), copper (Cu), and manganese (Mn). Results from analysis revealed that the amount of N, P, Ca, Na, and S was higher in microgreens, whereas a higher value for K was found in mature leaves. Zn, Cu, and Mn contents were found to be higher in mature leaves, while no significant difference was observed for Fe content in microgreens and mature leaves. The inclusion of celery microgreens in our daily diet would fulfill a significant portion of our daily mineral requirement. This is the first report on mineral comparison between microgreens and mature leaves of celery. It opens a new avenue for further enhancement of minerals via biofortification of this medicinal wonder crop through systematic breeding efforts. On the basis of mineral analysis, three genotypes, namely PAU2, PAU4, and PAU16, were found superior in terms of mineral composition in microgreens and mature leaves of celery. Principal component and cluster analyses divide the genotypes into two different clusters on the basis of variability in mineral composition.

Abstract
Background Patients with heart failure (HF) experience challenges in self-care that contribute to poor quality of life and high health care utilization. The COVID-19 pandemic required HF patients, especially living in countries with strict lockdowns and quarantines, to change their lifestyle including health promoting behaviors. Purpose To assess changes in self-care maintenance in patients with HF changed during quarantine compared to before quarantine. We hypothesized that the self-care maintenance behavior physical activity was most effected during quarantine. Method This is a cross-sectional survey study. From the medical chart, patients' disease severity (NYHA-class), ejection fraction and comorbidities were collected. Self-care maintenance was assessed using subscale Self-Care of Heart Failure Index 6.2. The total score ranges from 0–100, where 70 or higher is seen as having good self-care maintenance. With all the questions in the self-care maintenance scale a question was added: Did this change due to the COVID-19 pandemic? Patients could answer yes or no. When patients answered yes, they were asked the elaborate. Patients self-reported physical activity, before and during the pandemic, using the International Physical Activity Questionnaire (short form). Descriptive analyses were used for self-care maintenance, content analysis was applied for the qualitative data. Paired sample t-test were performed to assess the change in the total physical activity. Results In total, 120 patients with HF were included in this study (mean age was 79±13, 39% female, 78% NYHA-class I/II). Patients had a mean self-care maintenance of 32 (±6). No participant had good self-care maintenance (score of 70 or higher). Patients were non-adherent to regular physical activity (77%, n=92), keeping weight down (74%, n=89) and weighing themselves (66%, n=79) during quarantine (Figure). Behaviors which changed the most included keeping medical appointments (81%) and regular exercise (82%). Significantly higher levels of physically active was noticed before quarantine (776 Mets-minutes) compared to during quarantine (106 Mets-minutes) (p<0.01). The change in self-care maintenance was explained by change in motivation and self-confidence. Because of the pandemic and the quarantine, patients reported not being able to rely on health care and their usual social support system. Patients tried to create new habits when trying to maintain their self-care. Conclusion Patients with HF reported experiencing low self-care maintenance during quarantine due to not being able to go to medical appointments and decrease in physical activity. Public health policies during crisis events such as a pandemic should strive to provide support in coping with these changes and offer alternative ways of maintaining their self-care maintenance, especially with physical activity.

Abstract
Cotton cultivation is conquered by transgenic Bt upland cotton hybrids in India. Bt gene does not provide resistance against sucking insect pests. Due to the inherent vulnerability of extant Bt cotton hybrids to sap-sucking insect pests including leafhopper, upland cotton cultivation is seriously threatened by surging populations of these pests. Consistent and extensive screening of upland cotton germplasm over the years has revealed absence of adequate resistance against leafhopper. Here, we report introgression of leafhopper tolerance from a diploid A-genome cotton species, Gossypium arboreum into G. hirsutum. The dominance of leafhopper tolerance was observed over its susceptibility. Genetic analysis revealed that tolerance to leafhopper was inherited in a simple Mendelian fashion and was controlled by two genes, either singly or in combination. Using bulked segregant analysis, two simple-sequence repeat markers, namely NAU 922 and BNL 1705, located on chromosomes A5 and A11 respectively, were tagged with leafhopper tolerance. To the best of our knowledge, this is the first report of molecular tagging of leafhopper tolerance introgressed from G. arboreum into G. hirsutum. A significant negative association was observed between leaf trichome density and leafhopper nymph population.

Introduction
Several studies have demonstrated the effectiveness of telemedicine programmes in patients with coronary artery disease (CAD). However, the development of these programmes is driven from a technical point of view and does not usually take into account the needs and expectations of patients. Thus, we found a need to study the interests and preferences towards technology-based cardiac rehabilitation (CR) in patients with CAD.
Purpose
The aim of this study was to compare the interests and preferences towards technology-based CR in men and women with CAD.
Method
A cross-sectional study was conducted. A total of 70 subjects with CAD (84.28% male) were included. Participants' interests and preferences were measured using the Technology Usage Questionnaire, which includes items on digital health and technology usage.
Results
On the one hand, men showed a greater interest in receiving CR counselling via mobile phone (p=0.022), would sign up for a free technology-based CR programme (p=0.034) and would like to receive less than 1-2 messages a week (p=0.010). On the other hand, women showed greater interest in receiving information about the different components included in the CR programme (receiving healthy meal/recipe ideas (p=0.002), reminders to take medication (p=0.039) and showed greater interest in meeting other people with heart disease (p=0.034). No differences were found by gender in type of communication that participants would like to receive through their mobile phone (p=0.154) or through the Internet (p=0.648), interest in receiving treatment through the Internet (p=0.454), interest in receiving an exercise-based CR program using virtual reality (p=0.810), nor usefulness of a virtual CR session (p=0.801).
Conclusions
In subjects with CAD, gender appears to be a determinant of interest. Men showed a greater interest in receiving CR counselling via mobile phone, would sign up for a technology-based CR programme and would like to receive fewer notifications. Women were more interested in receiving information about different components of the CR programme.

Background
Recent studies show that cardiac telerehabilitation, including exercise and lifestyle modification, is effective in reducing cardiovascular risk factors in patients with coronary artery disease (CAD). Thus, physical activity and technology usage of patients with CAD are important key points in order to create technology-based cardiac rehabilitation programs to improve physical patients´ condition and reduce cardiovascular risk.
Purpose
The aim of this study was to compare the physical activity and the technological usage of women and men with CAD.
Methods
A cross-sectional study in patients with CAD was performed. Sociodemographic data, physical activity (measured with the International Physical Activity Questionnaire, IPAQ) and the technology usage (measured with the Technology use subscale of the Technology Usage Questionnaire) were collected. Descriptive and inferential analyzes were performed to explore the differences between men and women with CAD.
Results
A total of 70 participants were included (84.28% men, mean age=59±8.54 years). Regarding the IPAQ, men significantly reported higher walking time (99.31±95.22 METS vs. 33.28±37.42 METS, p=0.001, respectively) and higher total physical activity (4164.91±4164.91 METS vs. 1390.68±1609.05 METS, p<0.001, respectively) than women. In relation to technology usage, the entire sample used a mobile phone, whilst there were no significant gender differences in the functions/applications used (phone calls, text messages, camera, receive videos/photos, internet searches, apps, instant messages, social media, games) (p=0.068). Although the majority of the participants (85.71%) had regular access to internet, men used their phone more frequently than women (81.10% vs. 37.50%, p=0.005, respectively). Comparison by gender showed no significant differences in the type of device used for internet searches (computer, tablet, mobile phone) (p=0.169), familiarization with technology-based physical activity games (p=0.801), use of heart rate monitors (p=0.193), preference to monitor heart rate when exercising (p=0.664), nor use of other devices to monitor physical activity (pedometer, etc.) (p=0.193).
Conclusion
Based on the results obtained, we conclude that men with CAD were more physical active and used the Internet more often than women, whilst there were no differences by gender in the rest of variables. Assessment of physical activity and technology usage should be implemented in patients with CAD, in order to adapt and improve the design of technology-based telerehabilitation programs

Abstract
Cotton leaf curl disease (CLCuD), caused by a geminivirus complex, is the most serious disease of upland cotton in northwest India and Pakistan. It results in substantial losses in cotton yield and fibre quality. Due to continuous appearance of new viral strains, all the established CLCuD resistant stocks, extant and obsolete cultivars of upland cotton have become susceptible. Therefore, it became crucial to explore the novel sources of CLCuD resistance, as development of CLCuD resistant varieties is the most practical approach to manage this menace. Here, for the first time, we report introgression and mapping of CLCuD resistance from a 'synthetic cotton polyploid' to upland cotton. A backcross population (synthetic polyploid / Gossypium hirsutum Acc. PIL 43/G. hirsutum Acc. PIL 43) was developed for studying inheritance and mapping of CLCuD resistance. Dominance of CLCuD resistance was observed over its susceptibility. Two dominant genes were found to confer resistance to CLCuD. Molecular analysis through genotyping-by-sequencing revealed that chromosomes A01 and D07 harboured one CLCuD resistance gene each.

Abstract
Cotton has received attention of geneticists since more than a century. Gossypium hirsutum, the predominantly cultivated cotton species worldwide, has a narrow genetic base. It is important to broaden its genetic base through introgression of novel alleles from related species. Here, we report the development and characterization of a backcross population derived from the hybridization of a 'synthetic' (derived by crossing and chromosomal doubling of nonprogenitor Gossypium species) and natural tetraploid upland cotton. 'Synthetic' was observed to be male-sterile and thus, was used as the female parent. A total of 7434 flowers were pollinated to obtain 1868 BC1F1 seeds by direct and reciprocal crosses. Characterization of the experimental plant material was conducted in the field for several morphological traits such as pubescence on the stem, leaf, petiole and bract, presence/absence of petal spot, petal margin colouration and stamen filament colouration. Genetic analysis revealed that petal margin colouration phenotype was governed by a single dominant gene, whereas the petal spot and filament colouration phenotypes manifested segregation distortion. None of the BC1F1 plants was devoid of trichomes thus demonstrating that presence of trichomes is dominant over their absence. Modern upland cotton cultivars are usually devoid of petal spot, petal margin colouration and stamen filament colouration. These floral anthocyanin pigmentation characteristics, if fixed in the cotton germplasm, may serve as diagnostic features for the identification of cultivars during DUS testing as well as in the maintenance breeding programmes.

Abstract
Using gamma-ray-induced mutagenesis, we have developed a mutant (named G2) of Trichoderma virens that produced two- to three-fold excesses of secondary metabolites, including viridin, viridiol, and some yet-to-be identified compounds. Consequently, this mutant had improved antibiosis against the oomycete test pathogen Pythium aphanidermatum. A transcriptome analysis of the mutant vis-à-vis the wild-type strain showed upregulation of several secondary-metabolism-related genes. In addition, many genes predicted to be involved in mycoparasitism and plant interactions were also upregulated. We used tamarind seeds as a mass multiplication medium in solid-state fermentation and, using talcum powder as a carrier, developed a novel seed dressing formulation. A comparative evaluation of the wild type and the mutant in greenhouse under high disease pressure (using the test pathogen Sclerotium rolfsii) revealed superiority of the mutant over wild type in protecting chickpea (Cicer arietinum) seeds and seedlings from infection. We then undertook extensive field evaluation (replicated micro-plot trials, on-farm demonstration trials, and large-scale trials in farmers' fields) of our mutant-based formulation (named TrichoBARC) for management of collar rot (S. rolfsii) in chickpea and lentil (Lens culinaris) over multiple locations in India. In certain experiments, other available formulations were included for comparison. This formulation consistently, over multiple locations and years, improved seed germination, reduced seedling mortality, and improved plant growth and yield. We also noticed growth promotion, improved pod bearing, and early flowering (7-10 days) in TrichoBARC-treated chickpea and lentil plants under field conditions. In toxicological studies in animal models, this formulation exhibited no toxicity to mammals, birds, or fish.

Abstract
Tension pneumoperitoneum is a very rare consequence of acute gangrenous appendicitis. We report a case of a 32-year-old woman who presented with abdominal pain, progressively increasing abdominal distension, profound hemodynamic instability and ventilatory compromise. The diagnosis of tension pneumoperitoneum was confirmed by computed tomography, which showed compression of the intra-abdominal viscera and liver (saddlebag sign) by a large volume of intraperitoneal free air. Urgent needle decompression was done as an emergency measure. Exploratory laparotomy, planned due to persistent peritonitis, revealed gangrenous appendicitis with perforation near its base. Appendicectomy with excision of gangrenous portion of caecum was performed. The purpose of the reporting this case is to highlight that the tension pneumoperitoneum can be, very rarely, associated with gangrenous appendicitis and timely diagnosis is very important for the emergency management of this deadly condition.

Abstract
Traumatic abdominal wall hernia (TAWH) is a rare clinical entity in terms of aetiology. It occurs following a blunt abdominal injury with energy high enough to cause disruption of the musculoaponeurotic layer but not the elastic skin layer. It is often associated with underlying intra-abdominal injuries, which can be diagnosed either clinically or radiologically. We report a case of TAWH in a young man with associated large bowel transection, which remained undiagnosed in the preoperative period owing to its masked features. He was managed surgically, with no recurrence to date. Considering the high volume of blunt abdominal trauma cases that present to the accident and emergency department, only few cases of TAWH have been reported in the literature. Confusion still exists regarding the timing and mode of management of this condition.

Abstract
INTRODUCTION Little is known about the biology, molecular profile and hence optimal treatment of African Nigerian breast cancer. The aim of this work, therefore, was to characterize the histology and molecular profile of Nigerian breast cancer. METHODS Breast carcinomas from women at 6 centres of similar tribal origin in Nigeria were reviewed and assembled into tissue microarrays (TMAs), and sections were stained for hormone receptors, i.e. estrogen receptor (ER)α, ERβ1, ERβ progesterone receptor (PR) and androgen receptor, cyclin D, HER2, Ki67 and cytokeratins (CKs), i.e. CK5/6 and CK14 (basal) and CK18 and 19 (luminal). RESULTS A total of 835 tumours were analysed. The mean age at diagnosis was 48.62 ± 12.41 years. The most common histological subtype was ductal NST (no-special-type) carcinoma (87.3%). Over 90% of the tumours were grade 2 or 3. The predominant molecular phenotype was the non-basal, triple-negative type (47.65%) followed by the HER2-positive group (19.6%). The percentage of ER-, PR- and HER2-positive tumours was 22.4, 18.9 and 18.8%, respectively. CONCLUSION Nigerian breast cancer predominantly has a high-grade, triple-negative profile. It occurs at a younger age and bears similarities at the molecular level to pre-menopausal breast cancer in white women, with remarkably lower levels of ERβ expression. The early presentation and histological and molecular phenotype may explain the poor prognosis, and tailoring treatment strategies to target this unique profile are required.

Abstract
Comparative proteomic analyses were performed to detail the evolutionary consequences of strong directional selection for enhanced fiber traits in modern upland cotton (Gossypium hirsutum L.). Using two complementary proteomic approaches, 2-DE and iTRAQ LC-MS/MS, fiber proteomes were examined for four representative stages of fiber development. Approximately 1,000 protein features were characterized using each strategy, collectively resulting in the identification and functional categorization of 1,223 proteins. Unequal contributions of homoeologous proteins were detected for over a third of the fiber proteome, but overall expression was balanced with respect to the genome-of-origin in the allopolyploid G. hirsutum. About 30% of the proteins were differentially expressed during fiber development within wild and domesticated cotton. Notably, domestication was accompanied by a doubling of protein developmental dynamics for the period between 10 and 20 days following pollination. Expression levels of 240 iTRAQ proteins and 293 2-DE spots were altered by domestication, collectively representing multiple cellular and metabolic processes, including metabolism, energy, protein synthesis and destination, defense and stress response. Analyses of homoeolog-specific expression indicate that duplicated gene products in cotton fibers can be differently regulated in response to selection. These results demonstrate the power of proteomics for the analysis of crop domestication and phenotypic evolution.

Abstract
BACKGROUND Management of cardiac intensive care unit (ICU) sepsis is complicated by the high incidence of systemic inflammatory response syndrome, which mimics sepsis but without an infective cause. This pilot randomised trial investigated whether or not, in the ICU, 48 hours of broad-spectrum antibiotic treatment was adequate to safely treat suspected sepsis of unknown and unproven origin and also the predictive power of newer biomarkers of sepsis. OBJECTIVE The main objective of this pilot study was to provide preliminary data on the likely safety and efficacy of a reduced course of antibiotics for the treatment of ICU infections of unknown origin. DESIGN A pilot, single-centre, open-label randomised trial. SETTING This study was carried out in the ICU of a tertiary heart and chest hospital. PARTICIPANTS Patients being treated within the ICU were recruited into the trial if the intensivist was planning to commence antibiotics because of evidence of systemic inflammatory response syndrome and a strong suspicion of infection but there was no actual known source for that infection. INTERVENTIONS Broad-spectrum antibiotic treatment administered for 48 hours (experimental) compared with treatment for 7 days (control). MAIN OUTCOME MEASURES The primary outcome was a composite outcome of the rate of death or initiation of antibiotic therapy after the completion of the treatment schedule allocated at randomisation. Secondary outcomes included the duration of mechanical ventilation and ICU and hospital stay; the incidence of infection with Clostridium difficile (B. S. Weeks & E. Alcamo) Jones & Bartlett International Publishers, 2008, or methicillin-resistant Staphylococcus aureus (MRSA) (B. S. Weeks & E. Alcamo) Jones & Bartlett International Publishers, 2008; resource utilisation and costs associated with each of the two pilot arms; the ratio of patients screened to patients eligible to patients randomised; the incidence of crossover between groups; and the significance of newer biomarkers for sepsis for predicting patients' need for further antibiotics. RESULTS A total of 46 patients were recruited into the trial, with 23 randomised to each group. There was no significant difference between the two groups in terms of the composite primary outcome measure. The risk difference was 0.12 [95% confidence interval (CI) 0.11 to 0.13; p = 0.3]. In the 2-day group, four patients (17.4%) required further antibiotics compared with three (13%) in the 7-day group. Four patients died within the trial period and the deaths were not trial related. Patients who died during the trial period received no additional antibiotics in excess of their trial allocation. There were no documented incidences of MRSA or C. difficile infection in either group. No significant differences in adverse events were observed between the groups. Key economic findings were mean antibiotic costs per patient of £168.97 for the 2-day group and £375.86 for the 7-day group. The potential per annum cost saving for the ICU of 2-day treatment was estimated to range from £108,140 to £126,060. Patient screening was considered the biggest barrier to recruitment. There was no crossover between the two randomised groups. Data verification ascertained > 98% accuracy in data collection. Baseline procalcitonin was found to be predictive of the composite outcome (death and needing further antibiotics) (odds ratio 1.79, 95% CI 1.20 to 2.67; p = 0.005). Analysis of baseline procalcitonin also indicated a trend towards it being a predictor of restarting antibiotics, with an odds ratio of 1.45 (95% CI 1.04 to 2.02; p = 0.01). CONCLUSIONS Data from this pilot study suggest that there could be significant benefits of reducing broad-spectrum antibiotic use in the ICU without it undermining patient safety, with a potential cost saving in our unit of over £100,000 per year. Evidence from this pilot trial is not definitive but warrants further investigation using a large randomised controlled trial. TRIAL REGISTRATION Current Controlled Trials ISRCTN82694288.

Abstract
New quinazolin-4-one derivatives, 6-bromo-2-methyl-3-(substituted phenyl)-(3H)-quinazolin-4-one, were synthesized and evaluated for antimicrobial and antiinflammatory activities. The structures attributed to synthesized compounds 1-8 were supported by the results of elemental analysis as well as by the UV, IR and 1H NMR spectral data. Investigation of antimicrobial activity was performed using cup-plate agar diffusion method against Bacillus subtilis, Staphylococcus aureus and Pseudomonas aeruginosa and Candida albicans, Aspergillus niger and Curvularia lunata. Antiinflammatory activity was evaluated using the carrageenan-induced paw oedema test in rats. The results showed that compounds 2b, 2c, 2d, 2g and 2h exhibited significant antibacterial and antifungal activity comparable to standard drugs and compounds 2b and 2c showed good antiinflammatory activity comparable to ibuprofen.

Abstract
The gravitational-wave (GW) sky may include nearby pointlike sources as well as stochastic backgrounds. We perform two directional searches for persistent GWs using data from the LIGO S5 science run: one optimized for pointlike sources and one for arbitrary extended sources. Finding no evidence to support the detection of GWs, we present 90% confidence level (C.L.) upper-limit maps of GW strain power with typical values between 2-20×10(-50) strain(2) Hz(-1) and 5-35×10(-49) strain(2) Hz(-1) sr(-1) for pointlike and extended sources, respectively. The latter result is the first of its kind. We also set 90% C.L. limits on the narrow-band root-mean-square GW strain from interesting targets including Sco X-1, SN 1987A and the Galactic center as low as ≈7×10(-25) in the most sensitive frequency range near 160 Hz.

Abstract
Abstract
Introduction: Breast cancer in African women has been understudied for decades. Evidence derived mainly from studies on African-American women, supports that tumours of black women are biologically different and more aggressive than those occurring in the white population. Of the 4 main taxonomic groups of breast cancer, basal tumours are more represented in those women. In the present state of knowledge, very little is known about the biology and molecular profile of breast cancer in Africa. The aim of this study was to test the hypothesis that the molecular profile of African breast cancer is distinct from its Western counterpart. This was achieved by collecting a large cohort of breast carcinomas from an indigenous African population for phenotypical characterization and testing for expression of potential predictive and prognostic markers.
Methods: Breast tumours were collected via collaboration with five centres in Nigeria (the most populous country in Africa) and assembled into tissue microarrays (TMAs). All tumours were reviewed by a specialist breast pathologist following the Royal College of Pathologists (RCPath) guidelines to confirm diagnosis, type, grade and nodal status. Patients age, tumour size and clinical data, where available, were collected from the original pathology reports and case notes. Representative tumour areas were selected and marked for TMA construction. TMA sections were stained for a range of markers including hormone receptors (ERα, ERβ, PR, AR), cyclin D, HER2, Ki67, bcl2, basal (CK5/6, CK14) and luminal cytokeratins (CK18, 19).
Results: A total of 830 tumours were assembled into TMAs. The mean age at diagnosis was 47.69yrs with 58% of patients presenting under the age of 50. Only 8.5% of tumours were of grade 1. Most tumours (87%) were of ductal no special type, followed by lobular and metaplastic carcinomas. The majority of the tumours were ERα, PR and HER2 negative (77%, 80% and 81% respectively). The triple negative tumours were the predominant phenotype (55.6%). Luminal A type tumours comprised 24.3% followed by the HER2 positive (13.9%) and luminal B tumours (6.2%). The differences of all those parameters were statistically highly significant (p<0.001). Most tumours expressed ERß including 75% of those that were ERα/PR negative. A large proportion of the tumours (22%) were of the basal phenotype of which two thirds were also triple negative. Over half of the triple negative tumours were also node positive.
Hierarchal cluster analysis showed the basal tumours dendrogram to comprise two groups; one showing clustering of ***ERα/PR/HER2 and the second showing clustering of ERß with CK5 and CK14.
Conclusion: To our knowledge, this is largest and most comprehensive study of African breast cancer to date. Our data confirms the hypothesis that African breast cancer is biologically distinct and shows remarkable differences in histological type, grade, hormone receptors & HER2 status when compared with breast cancer in white women. The early age at presentation, predominance of high grade and triple negative, but not necessarily basal phenotype, may explain the poor prognosis and requires tailoring treatment strategies to target this unique profile.

Abstract
Calotropis procera, belonging to the Asclepidaceae family, is present more or less throughout India and in other warm, dry places such as, Warizistan, Afghanistan, Egypt, and tropical Africa. Its common names are Akra, Akanal, and Madar. The leaves of Calotropis procera are said to be valuable as an antidote for snake bite, sinus fistula, rheumatism, mumps, burn injuries, and body pain. The leaves of Calotropis procera are also used to treat jaundice. A study on Calotropis procera leaf samples extracted the air-dried leaf powder with different solvents such as petroleum-ether (60-80°C), benzene, chloroform, ethanol, and sterile water. Preliminary phytochemical analysis was done long with measurement of the leaf constants, fluorescence characteristics, and extractive values. Quantitative estimation of total ash value, acid insoluble ash, and water- soluble ash may serve as useful indices for identification of the powdered drug. Histochemical studies which reveal rows of cylindrical palisade cells and, vascular bundles may also serve as useful indices for identification of the tissues. These studies suggested that the observed pharmacognostic and physiochemical parameters are of great value in quality control and formulation development of Calotropis procera.

Abstract
BACKGROUND Cancer data from Rajasthan are limited. Only two studies, one from Western Rajasthan, and the other from Eastern Rajasthan have been published by Sharma et al. in 1992 and 1996. AIMS To put the cancer profile from this region in proper perspective, we conducted the present study on the patterns of various malignancies in Jaipur region, i.e., Eastern Rajasthan. SETTING AND DESIGN AND MATERIAL AND METHODS: The study spans over one and half decade (1990-2004) and is based on a retrospective six-year sample analysis of approximately 200,000 histopathological and cytological reports for the years 1990, 1991, 1996, 1999, 2001 and 2004. RESULTS A total of 21,868 cancers were recorded in the six sample years. There were 59.11% (12,926) males and 40.89% (8942) females, with the male to female ratio being 1.45:1. Organ wise, lung (8.45%), prostate (7.12%), brain (6.04%), urinary bladder (5.31%), esophagus (4.67%) and tongue (4.60%) are most common sites involved in males with regard to frequency, whereas breast (20.44%), cervix (14.99%), ovary (4.35%), brain (3.80%), esophagus (3.67%), uterus (3.01%) and rectum (2.80%) are common sites for malignancies in females. CONCLUSIONS Significant findings were a higher frequency of cancers of the prostate, urinary bladder, and brain in males along with gall bladder cancers in females. Our figures have been compared with the national data.

Abstract
Poor solubility and poor permeability account for many pharmacokinetic failures and about thirty percent of drug molecules are rejected due to pharmacokinetic failures. When poor pharmaceutical properties are discovered in development, the cost of bringing a potent, but poorly absorbable molecule to the product stage by formulation can become very high. Fast and reliable in vitro prediction strategies are needed to filter out problematic molecules at the earliest stage of discovery. This communication will consider recent developments in physiochemical profiles used to identify molecules with physical properties related to good oral absorption. FDA's biopharmaceutical classification system (BCS) is an attempt to rationalize the critical components related to oral absorption and utilization of these principles for selection of a suitable technology to serve the interests of the early stages of drug discovery.

Abstract
Infertility is a major health problem affecting about 10-20% of couples in the reproductive age group. Male factor is assumed to be responsible in about 50% cases of infertility. The origin of reduced testicular sperm function is unknown in about 50-70% of cases and for such couples assisted reproduction techniques (ART) are a boon. Male infertility is often due to poor semen quality and may be associated with genetic defects. ART has revolutionized management of infertility and intracytoplasmic sperm injection (ICSI) is the ART procedure of choice in 60-80% cases. Despite major technological advancements and professional expertise in ART, the success rate and carry-home live birth rate of ICSI is low (18-25%). This study was aimed to understand the genetic etiopathology of recurrent ART failure. For this, 110 couples with 3 or more failed ART cycles were recruited. A detailed history was taken and only idiopathic ART failure cases were enrolled for this study. They were subjected to cytogenetic and Yq microdeletion analysis. Genetic abnormalities were detected in 19 couples. Since a large number (18.2%) cases harboured genetic abnormalities, it is important for all couples opting for ART to undergo a thorough genetic analysis to prevent recurrent emotional, physical and financial stress.

Abstract
Trichosporon asahii is a basidiomycetous yeast which causes white piedra and onychomycosis in immunocompetent hosts as well as various localized and disseminated invasive infections in immunodeficient hosts. Urinary tract infection caused by Trichosporon asahii is rare. One month after posterior urethral valve surgery a seven-month-old male child presented with fever, severe vomiting and crying on micturition for five--to six days. Yeast-like fungus was isolated in pure cultures from three consecutive urine samples. It was identified as Trichosporon asahii using standard techniques. The response to antifungal therapy was dramatic. To the best of our knowledge this is the first report of a urinary tract infection caused by Trichosporon asahii from Western India.

Abstract
Ontologies are specifications of the concepts in a given field, and of the relationships among those concepts. The development of ontologies for molecular-biology information and the sharing of those ontologies within the bioinformatics community are central problems in bioinformatics. If the bioinformatics community is to share ontologies effectively, ontologies must be exchanged in a form that uses standardized syntax and semantics. This paper reports on an effort among the authors to evaluate alternative ontology-exchange languages, and to recommend one or more languages for use within the larger bioinformatics community. The study selected a set of candidate languages, and defined a set of capabilities that the ideal ontology-exchange language should satisfy. The study scored the languages according to the degree to which they satisfied each capability. In addition, the authors performed several ontology-exchange experiments with the two languages that received the highest scores: OML and Ontolingua. The result of those experiments, and the main conclusion of this study, was that the frame-based semantic model of Ontolingua is preferable to the conceptual graph model of OML, but that the XML-based syntax of OML is preferable to the Lisp-based syntax of Ontolingua.

Abstract
Cruciferous vegetable extracts from freeze-dried cabbage (FDC), freeze-dried fermented cabbage (FDS), and acidified Brussels sprouts (ABS) were prepared by exhaustive extraction with ethyl acetate. Estrogenic and antiestrogenic effects of these extracts were analyzed. To identify whether the extracts are potential estrogen receptor (ER) ligands that can act as agonists or antagonists, the binding affinity of extracts for the ER was measured using a competitive radiometric binding assay. The extracts bound with low affinity to the ER, and the relative binding affinity is estradiol > FDS > FDC > ABS. These extracts were evaluated for their estrogenic and antiestrogenic activities in estrogen-dependent human breast cancer (MCF-7) cells using as endpoints proliferation and induction of estrogen-responsive pS2 gene expression, which was analyzed using Northern blot assay. At low concentrations (5-25 ng/mL) all of the extracts reduced 1 nM estradiol-induced MCF-7 cell proliferation. Extracts at 25 ng/mL also inhibited estradiol-induced pS2 mRNA expression. At higher extract concentrations (50 ng/mL-25 microg/mL), however, increased proliferation in MCF-7 cells was observed. Similarly, expression of the pS2 gene was induced by higher extract concentrations (0.25-25 microg/mL). The pure estrogen antagonist, ICI 182,780, suppressed the cell proliferation induced by the extracts as well as by estradiol and also the induction of pS2 expression by the extracts. The ER subtype-selective activities of FDC and FDS were analyzed using a transfection assay in human endometrial adenocarcinoma (HEC-1) cells. FDS acted as an ERalpha-selective agonist while FDC fully activated both ER-alpha and ER-beta. Growth of the ER-negative MDA-231 cells was not affected by the extracts or by estradiol. This study demonstrates that cruciferous vegetable extracts act bifunctionally, like an antiestrogen at low concentrations and an estrogen agonist at high concentrations.

Abstract
UNLABELLED Three myosin isozymes, V1 (alphaalpha MHC = Myosin Heavy Chain gene), V2 (alphabeta MHC) and V3 (betaalpha MHC) that are identified in the cardiac ventricles of most mammals have been shown to shift to a V3 predominance pattern during cardiac growth and in response to left ventricular pressure overload, and to V1 predominance following anti hypertensive treatment. This study examined whether long-term hypertension impairs the ability of the adult heart to restructure myosin isozyme proportions. Using pyrophosphate gel electrophoresis, we studied proportions of cardiac myosin isozymes (V1 and V3) in young (16 weeks) and adult (36 weeks) spontaneously hypertensive rats (SHR), and following 12 weeks of nifedipine (N) treatment in age-matched SHR rats (SHR-N). The values of V1 and V3 myosin isozymes were derived by adding half of the value of V2 to each isozyme proportion. The V3 proportion in the young SHR control (SHR-C) group (49%) was 34% higher (p < 0.05) than in the young Wistar Kyoto control (WKY-C) group (37%). However, the proportion was similarly high, though not statistically significant, in both the adult SHRC (73%) and WKY-C (71%) groups. The proportion in the young SHR-N group (29%) was 41% lower (p < 0.05) than in the young SHR-C group (49%), and the proportion in the adult SHR-N group (47%) was 34% lower (p < 0.05) than in the adult SHR-C group (73%). The ratio of left ventricular weight to body weight (LVW/BW), which determines left ventricular hypertrophy (LVH), was higher in both young and adult SHR-C (26%, p < 0.05, and 42%, p < 0.05, respectively) than in WKY-C groups. The mean LVW/BW was 27% (p < 0.05) greater in adult than in young SHR-C rats. The LVW/BW in both age groups of treated SHR-N was similar to that in age matched WKY-C rats. CONCLUSION Our study showed that a rise in the V3 level occurs in young hypertensive rats, but no rise occurs in the V3 level in adult hypertensive rats. High blood pressure seems to contribute to the high V3 level in young hypertensive rats, but in adult hypertensive rats, high blood pressure does not accentuate the V3 rise already acquired due to the aging process. Nifedipine treatment in both young and adult hypertensive rats prevented the V3 rise due to hypertension and to the aging process. This effect of nifedipine seems to be through its antihypertensive action.
