suicide is a major public health concern, with approximately one million people committing suicide world-wide each year .risk factors for suicidal behavior include, psychiatric and medical illness, impulsivity, aggression, alcohol and drug abuse specially stimulants, and  stress. neurobiological, brain mappings and biochemical studies have revealed that suicide victims experiencing a large numb...

The transcription factor Sip1 (Zeb2) plays multiple roles during CNS development from early acquisition of neural fate to cortical neurogenesis and gliogenesis. In humans, SIP1 (ZEB2) haploinsufficiency leads to Mowat-Wilson syndrome, a complex congenital anomaly including intellectual disability, epilepsy and Hirschsprung disease. Here we uncover the role of Sip1 in retinogenesis. Somatic dele...

The concept of CNS preventive therapy in childhood all is based on the assumption that undetectable CNS leukemia is present in most patients at the time of diagnosis, residing in that "sdnctuary site" protected by the blood-brain barrier from cytotoxic concentrations of most systemically ad­ministered antileukemic agents. Studies in the 1960s demonstrated that administration of 2400 rad cranial...

Mutations in chromosome-helicase-DNA-binding protein 7 (CHD7) are identified as the main cause for CHARGE syndrome (coloboma, heart anomaly, choanal atresia, retardation, genital and ear anomalies). Most patients (55% to 85%) with CHARGE syndrome display developmental defects in the central nervous system (CNS), of which pathology and molecular mechanisms remain unclear. In this study, we repor...

Emerging pollutants are an increasing problem in wastewater globally. Bisphenol A (BPA) is one compound belonging to this group. This work proposes the study of employment several metal-supported (2 wt. %) carbon nanospheres (CNS) for BPA degradation by catalytic wet-air oxidation. Several techniques were used catalyst characterization: thermogravimetry, X-ray diffractometry (XRD), Fourier tran...

BACKGROUND AND PURPOSE Although sonography is the primary imaging technique for evaluating the developing fetus, significant limitations exist in the sonographic prenatal diagnosis of many brain disorders. Fast MR imaging is increasingly being used to determine the underlying cause of nonspecific fetal CNS abnormalities detected sonographically and to confirm or provide further support for such...

introduction: nager syndrome is a malformation resulting from problems in the development of the first and second branchial arches and limb buds. the cause of the abnormal development of the pharyngeal arches in nager syndrome is unknown. it is also unclear why affected individuals have bone abnormalities in their arms and legs. nager syndrome is thought to have an autosomal recessive inheritan...

turner syndrome is one of the best known chromosome anomalies in human being, by an approximate incidence of 1/2500 female at birth. the cause is a chromosomal aberration, mainly with the karyotype 45, x. ninety six patients aged 6 to 26 years with short stature were studied for chromosomal anomalies. out of these 82 were phenotypically female and 14 phenotypically male. twenty seven showed abn...
