Although the midline and lateral neck masses differ considerably in their texture and presentation but the embryological perspective of these masses is not mostly understood along with the fundamental anatomical knowledge. The article tries to correlate the embryological, anatomical and clinical perspectives for the same

A histological study of prostate

The work of anatomists and pathologists in the role of study of prostate has been significant. Starting from earlier times till modern time, the study of prostate has been a dynamic one and the basic anatomical knowledge of the prostate has undergone much change apart from the new techniques, micro invasive procedures and the chemotherapeutic approach for various disorders of the gland. The present study was based on the microscopic examination of Prostatic tissue of individuals with individual tissues of different age groups. The present study involved 40 cases which were further subdivided into various age groups and characteristic histological changes were noted. The study presents an assessment of age changes in prostate in elderly in Kashmiri population with pathological significance. Besides the histological study is of great importance in staging of diseases of prostate and especially in modern era where the incidence and prevalence of prostatic diseases is on rise

The anatomical, surgical and orthopedic importance of gastrocnemius

Gastrocnemius is one of the most important muscles of lower limb. It belongs to the superficial compartment of calf muscles. They belong to group of superficial flexors. Gastrocnemius, plantaris and soleus form the bulk of the calf. Gastrocnemius forms the belly of the calf. It arises by two distinct heads, connected to the condyles of the femur by strong, flat tendons. It has an immense anatomic, medical, orthopedic and physiological importance and is attributed in a variety of medical and surgical problems. A profound knowledge of this muscle is of great importance to any surgeon or orthopedicians or any clinician

ISOLATION OF EGG DROP SYNDROME VIRUS AND ITS MOLECULAR CHARACTERIZATION USING SODIUM DODECYL SULPHATE POLYACRYLAMIDE GEL ELECTROPHORESIS

Six isolates of egg drop syndrome (EDS) virus were recovered from five different outbreaks of EDS in commercial laying hens in and around Faisalabad. The aberrant eggs were fed to the susceptible laying hens for experimental induction of infection. The samples from infected birds (egg washing, cloacal swabs, oviducts and spleens) were collected, processed and inoculated into 11-day old duck embryos. The presence of virus in harvested allanto-amniotic fluid was monitored by spot and microhaemagglutination tests and confirmed by haemagglutination inhibition and agar gel precipitation tests. The EDS virus grew well in duck embryos and agglutinated only avian but not mammalian red blood cells. These isolates were purified through velocity density gradient centrifugation. Protein concentration was determined through Lowry method and sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) was conducted by loading 300 µg protein concentration on 12.5% gel using discontinuous buffer system. All the six isolates showed 13 polypeptides, which were identical to those described in the referral EDS-76 virus (strain-127). The molecular weights of the polypeptides ranged from 6.5 KDa to 126 KDa

The specimens were collected from subjects diagnosed as colorectal carcinomas in histopathology department and clinical details were sought from the medical records. Variables like age, sex, dietary habit, relevant history, tumor size, location, type of lesion, histological pattern of patients were checked.Results:In the series of 446 patients of colorectal neoplasm, maximum number of patients presented in 4th to 6th decade of life (47.30%), while as (15.46%) were between 20-40 years. The youngest patient with an adenocarcinoma was 18 years (male) of age and the oldest one was 80 years (male) of age. Average age of patients was 50.50 years. The male to female ratio was 1.3:1. The study revealed that the carcinoma of ascending colon was much more prevalent, constituting 107 (40.07%) cases. The proportion of well differentiated carcinoma was highest in left side colon and rectum. The incidence of moderately differentiated and poorly differentiated carcinoma was greater on right side colon.Conclusion:Adenocarcinoma is the most common histological variant of colon carcinomas.

PREPARATION OF CONJUGATE FOR USE IN AN ELISA FOR HUMORAL IMMUNE RESPONSE AGAINST EGG DROP SYNDROME VIRUS IN LAYER CHICKS

An indirect enzyme-linked immunosorbent assay (ELISA) was performed for the detection of antibodies against Egg Drop Syndrome (EDS) virus. Virus identification was done through haemaggluti- nation inhibition (HI) test using known antisera. Antichicken immunoglobulins were raised in goats and purified by ammonium sulphate precipitation technique. These goat-antichicken immunoglobulins were conjugated with horseradish peroxidase. Twenty-seven serum samples were collected from a layers flock vaccinated against EDS and specific antibodies were determined by using a horseradish conjugate

Intrusion Detection Systems in Cloud Computing: A Contemporary Review of Techniques and Solutions

Rapid growth of resources and escalating cost of infrastructure is leading organizations to adopt cloud computing. Cloud computing provides high performance, efficient utilization, and on-demand availability of resources. However, the cloud environment is vulnerable to different kinds of intrusion attacks which involve installing malicious software and creating backdoors. In a cloud environment, where businesses have hosted important and critical data, the security of underlying technologies becomes crucial. To mitigate the threat to cloud environments, Intrusion Detection Systems (IDS) are a layer of defense. The aim of this survey paper is to review IDS techniques proposed for the cloud. To achieve this objective, the first step is defining the limitations and unique characteristics of each technique. The second step is establishing the criteria to evaluate IDS architectures. In this paper, the criteria used is derived from basic characteristics of cloud. Next step is a comparative analysis of various existing intrusion detection techniques against the criteria. The last step is on the discussion of drawbacks and open issues, comprehended from the evaluation, due to which implementation of IDS in cloud environment face hurdles

Genetic study in congenital heart defects

Background: Congenital heart diseases (CHD) are relatively common with a prevalence ranging from 3.7 to 17.5 per 1000 live births. Little is known about genetic link with respect to congenital heart disease. Iroquoise (Irx) homeobox genes have been widely studied and their expression in both developing and adult heart. Author tried to study the role of irx4 and irx5 genes in structural congenital heart disease, keeping the focus on study reported by Cheng Z et al.Methods: Author studied reported mutation site sequences in 25 various congenital heart disease patients and control healthy relatives of patients. It is a unique study and there has not been such a study reported in literature till date. Besides comparison with healthy related controls, author took cardiac tissue biopsy in patients while doing corrective cardiac surgery. However, blood samples were taken from controls due to ease of feasibility.Results: Although, there were no sequence variations in the studied exon regions, but author got a base pair sequence change at 6 bp intron region, which is near the exon splice site in irx4 gene. Besides two ASD patient’s male children (one child each) had ASD prompting us to believe some role of sex linkage. However later needs pedigree analysis and sex chromosome studies for further analysis.Conclusions: Gene sequence in the Kashmiri population is unique. There is possibility of role of irx genes in CHD. ASD might have sex linkage in some
