Background Infertility and fertility decline are quite a conundrum for medicine, rampant among 10-15 percent of couples. In about 40 percent of cases, men are the main culprit. Since sperm production disorders are the focal cause of man infertility, insights into these disorders and taking action to ameliorate the situation is quite vital. The current study concentrates on infertility due to sp...

Aim: To investigate the prevalence of eight morphological and numerical anomalies in the southern Chinese permanent dentition and to compare these with studies from different populations. Materials and Methods: The material used in the study consisted of study models and panoramic radiographs collected from 725 randomly selected 12-year-old children (358 males and 367 females). The anomalies we...

introduction robinow syndrome (rs) is an infrequent genetic condition that is characterized by a dysmorphic face, dental anomaly, short stature, mesomelic limb shortening, hand and foot anomalies, and hypoplastic genitalia. the robinow syndrome has been reported from the arab countries and other asian countries, but has not been reported in iranian population so far. case presentation a new bor...

The thyroid gland is the first endocrine gland to start developing in the embryo. Morphological and structural developmental anomalies of the thyroid gland are relatively rare. Thyroid developmental anomalies (TDA) (excluding biochemical abnormalities) can be divided into three groups namely agenesis (or athyreosis), dysgenesis, and anomalies due to persistence of the thyroglossal tract (Jain a...

Background: Ultrasound imaging is an effective and routine diagnostic tool for identifying fetal anomalies. The congenital defect of Pentalogy of Cantrell, also known as Thoracoabdominal Ectopia, consists of 5 defects that include a cleft lower sternum, an anterior diaphragmatic defect, and the absence of the parietal pericardium, a connected or separate omphalocele, and a major cardiac anomaly...

[1] We show a set of forward model equations in the Fourier domain for calculating the 3-D gravity and magnetic anomalies of a given 3-D distribution of density or magnetization. One property of the potential field equations is that they are given by convolution products, providing a very simple analytic expression in the Fourier domain. Under this assumption, the domain of the density or magne...

Animal models are of great importance for medical research. They have enabled analysis of the aetiology and pathogenesis of complex congenital malformations and have also led to major advances in the surgical and therapeutic management of these conditions. Animal models allow us to comprehend the morphological and molecular basis of disease and consequently to discover novel approaches for both...

The first aspect of chronic pancreatitis (CP) is the early phase of relapsing pancreatitis (RP) in which episodes of mild acute pancreatitis (MAP) or severe acute pancreatitis (SAP) occur repeatedly over a period of time [1, 2]. In RP modifications occur mainly at the ductal structures. These can be functional (altered response to secretin administration, late discharge of pancreatic juices int...

BACKGROUND Cognitive deficits are a core feature of early schizophrenia. However, the pathological foundations underlying cognitive deficits are still unknown. The present study examined the association between gray matter density and cognitive deficits in first-episode schizophrenia. METHOD Structural magnetic resonance imaging of the brain was performed in 34 first-episode schizophrenia pat...
