Objective(s): Epidermolysis bullosa is one of the most important series of mechano-bullous heritable skin disorders which is categorized into four major types according to the layer that bullae forms within basement membrane zone. In dystrophic form of the disease, blisters are made in the sublamina densa zone, at the level of type VII collagen protein which produce anchoring fibrils. Type VII ...

Background: Gastric cancer (GC) is considered as one of the most common types of cancer worldwide with poor prognosis and generally limited treatment options. Recent studies have indicated that HER2, MDM2, MYC, MET, and TP53 play an important role in the development of gastric cancer. Therefore, the aim of this study was to evaluate the incidence of amplification/deletion of these genes in pati...

Background & Aims: Pseudomonas aeruginosa is a gram-negative opportunistic pathogen and one of the mortality causes of nosocomial infections. One of the drug resistance mechanisms in P.aeruginosa is mutation in negative regulator genes of mexAB-oprM efflux pump system such as nalD. The aim of this study was to investigate the role of nalD mutations in P. aeruginosa isolates of Guilan province i...

Objective(s): Fibromyalgia pain is a mysterious clinical pain syndrome, characterized by inflammation in the brain, whose molecular mechanisms are still unknown. Females are more commonly affected by fibromyalgia, exhibiting symptoms such as widespread mechanical pain, immune dysfunction, sleep disturbances, and poor quality of life. Electroacupuncture (EA) has been us...

Background: Disorders of sex development (DSDs) belong to uncommon pathologies and result from abnormalities during gonadal determination and differentiation. Various gene mutations involved in gonadal determination and differentiation have been associated with gonadal dysgenesis. Despite advances in exploration of genes and mechanisms involved in sex disorders, most children with severe 46,XY ...

Deletions of the DAZ gene family in distal Yq11 are always associated with deletions of the azoospermia factor c (AZFc) region, which we now estimate extends to 4.94 Mb. Because more Y gene families are located in this chromosomal region, and are expressed like the DAZ gene family only in the male germ line, the testicular pathology associated with complete AZFc deletions cannot predict the fun...

X—linked agammaglobulinemia (XLA, OMIM #300755) is a primary immunodeficiency disorder caused by pathogenic variations in the BTK gene, characterized failure of development and maturation B lymphocytes. The estimated prevalence worldwide 1 190,000 male births. Recently, genome sequencing has been widely used difficult to diagnose familial cases. We report large Indian family suffering from XLA ...
