Seasonal changes in mood and behavior (seasonality) may be closely related to alcoholism. Some patients with alcoholism have a seasonal pattern to their alcohol misuse. They may be self-medicating an underlying seasonal affective disorder (SAD) with alcohol or manifesting a seasonal pattern to alcohol-induced depression. Both genetic and environmental factors play a role in the etiology and pat...

effects of nitrogen fertilization timing close to the beginning of short-day period and white mulch on flowering and yield components have been studied in ‘paros’ and ‘queen elisa’ strawberry cultivars. split plot experiment in a randomized complete block design with eight treatments (two mulch treatments × n fertilization during four different times from last week of august to third week of se...

a study was conducted in the northeastern areas of punjab province (pakistan) to analyse the monthlyand seasonal pattern of fasciolosis in buffaloes and its relation to some climatic factors (temperature,humidity, rainfall and pan-evaporation) was also worked out. the faecal samples of buffaloes were collectedfrom april 2003 to march 2005 on a monthly basis from randomly selected areas and anal...

background: secretory proteins of ige receptor activated mast cells and basophils play a pivotal role in the generation of immediate and long term immune responses in allergy and type i hypersensitivity. objective: the present study aims to generate a 2-d map and profile of proteins secreted from a high secretory variant of the rat basophilic leukemia cell line, rbl-2h3.1, which in view of the ...

Tardigrades are able to tolerate almost complete dehydration by reversibly switching to an ametabolic state. This ability is called anhydrobiosis. In the anhydrobiotic state, tardigrades can withstand various extreme environments including space, but their molecular basis remains largely unknown. Late embryogenesis abundant (LEA) proteins are heat-soluble proteins and can prevent protein-aggreg...

Background Effect of seasonal changes in human reproduction has been intensively researched. Some studies acknowledge influences of seasonal variation on natural conception, while others can not confirm them. The aim of this study was to investigate the effect of seasonal changes on different stages of assisted reproductive technology (ART) in Tehran. MaterialsAndMethods This study was carried ...

The hibernator's heart functions continuously and avoids damage across the wide temperature range of winter heterothermy. To define the molecular basis of this phenotype, we quantified proteomic changes in the 13-lined ground squirrel heart among eight distinct physiological states encompassing the hibernator's year. Unsupervised clustering revealed a prominent seasonal separation between the s...

Small passerine birds in the north need to take advantage of several behavioral and physiological mechanisms maintain energy balance during winter characterized by low food supply, ambient temperatures, short days. Here we test if breathing pattern a non-migratory species, great tit ( Parus major ), show seasonal variation that could help species keeping positive winter. To this aim, measured o...
