Increasing effort is directed toward elucidating the mechanisms by which guanine nucleotide-binding proteins regulate specific cellular processes. A common feature of this class of proteins is that GTP induces a transition from an inactive to an active conformation. The latter is limited by the hydrolysis of GTP and the coincident production of GDP. Here we provide evidence that guanine nucleot...
Received 12 November 1996 and in revised form 16 January 1997 Accepted 14 February 1997 Abstract Background-Charcot-Marie-Tooth disease type 2 (CMT2) or hereditary motor and sensory neuropathy type II (HMSN II) is an inherited axonal neuropathy of the peripheral nervous system. Three autosomal dominant CMT2 loci have been located on chromosomes lp35-p36 (CMT2A), 3ql3-q22 (CMT2B), and 7pl4 (CMT2...
Horizontal connections in area 17 of adult cats and ferrets link cells with similar preferred orientations by a patchy network of projections extending several millimeters across the cortex. The maturation of orientation selectivity in ferret area 17 has been demonstrated previously by quantitative single-unit recording and optical imaging to begin at approximately postnatal days (P) 32-P36. We...
The lateral superior olive (LSO), a conspicuous mammalian brainstem nucleus that is involved in sound localization, has become a model system for investigating the formation of topographically organized inhibitory and excitatory connections. In experiments employing intracellular injections of Lucifer yellow or neurobiotin into lightly fixed brain slices, we have examined the soma-dendritic mor...
Plasmodium sporozoites, the mosquito-transmitted forms of the malaria parasite, first infect the liver for an initial round of replication before the emergence of pathogenic blood stages. Sporozoites represent attractive targets for antimalarial preventive strategies, yet the mechanisms of parasite entry into hepatocytes remain poorly understood. Here we show that the two main species causing m...
Toxoplasma gondii has recently come under intense study as a model for intracellular parasitism because it has a number of properties that facilitate experimental manipulation. Attention is now being turned towards understanding the developmental biology of this complex parasite. The differentiation between the two asexual stages, the rapidly growing tachyzoites and the more slowly dividing, en...
گسترش پوششهای بیمهای و حمایتی و نظام تأمین اجتماعی سبب افزایش امید به زندگی، بهبود وضعیت و کیفیت زندگی افراد، افزایش سطح فرهنگی و بهداشتی، کاهش فقر و متعادل نمودن توزیع درآمد، کاهش ریسک و نااطمینانی نیروی کار در سالهای آتی (بازنشستگی) و تأثیر کلی آن در عرصههای مختلف زندگی (اقتصادی ـ اجتماعی) میشود، لذا در مطالعه حاضر ارتباط تأمین اجتماعی با شاخص توسعه انسانی در ایران مورد بررسی قرار گرفته ...
Abstract Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that affects approximately 0.8% of the UK population. A survey was carried out among patients attending tertiary HS clinic with aim better understanding management in primary care, and identifying prevalence associated risk factors. total 212 552 (38.4%) invited chose to participate. The length time had experienced sy...
