black bengal goat is the heritage and one of the potential genetic resources of bangladesh. genetic and phenotypic parameters for semen characteristics and their relationships with scrotal circumference in black bengal bucks were estimated in this experiment. genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanen...

background : multiple sclerosis (ms) is an autoimmune disease with unknown factor. the prevalence and incidence rate of this disease had an upward trend in many regions in the world such as middle east and consequently in iran over the recent years. as the risk factors of this increased trend and high-prevalence is unknown in iran, the current study has been designed to evaluate the correlation...

Today, the quality of services is an increasingly important factor in the success and survival of the banking sector. Therefore, the discovery of effective factors in the quality of services and the importance of each of these factors is very important from the point of view of customers due to the increasing intensity of competition. Modern com- merce requires appropriate tools and infrastruct...

Maize (Zea mays L.) breeders have begun selecting for more compact plants for higher density planting in order to increase yield per unit area. Leaf angle and leaf orientation are very important traits affecting maize plant type (compactness). In this study, a genetic linkage map containing 138 simple sequence repeat (SSR) markers was constructed based on a mapping population consisting of 500 ...

Vitamin A and its analogs (retinoids) have shown great prom ise for the chemoprevention of cancer as well as being a possible new class of chemotherapeutic agents. A Phase I and II trial of 13-c/s-retinoic acid in advanced cancers was initiated, and the clinical pharmacology of the drug was studied. All patients received p.o. 13-c/s-retinoic acid starting at 0.5 mg/ kg/day, escalating over 4 we...

Background: Antenatal renal pelvis dilatation (RPD) is the most common congenital anomaly detected on antenatal ul-trasound. The present study was planned to determine characteristics and outcome of neonates with pel-vis dilatation. Patients Methods: A prospective, observational, non-interventional conducted in Fatima Memorial Hospital over a period 12 months from April 2021 March 2022. This in...

Many agriculturally important traits are complex, affected by many genes and the environment. Quantitative trait loci (QTL) mapping is a key tool for studying the genetic structure of complex traits in plants. In the present study QTLs associated with yield and agronomical traits such as leaf number, leaf length, leaf width, plant height, stem and head diameter were identified by using 70 recom...

to estimate heritability and genetic trend for 305-d milk production and lactation persistency, a total of 130,668 monthly test day milk yields belonging to 15,183 first lactation holstein cows in 131 herds and calved from 2000 to 2009 were used. to calculate 305-d milk yield as well as lactation persistency, estimated parameters of wilmink’s exponential function were applied. the parameters of...
