A New Species of Group (Reptilia: Squamata: Gekkonidae) from Xizang Autonomous Region, China.

A new species, , from the dry-hot valleys near the Yarlung Zangbo River in Re Village, Jindong Countryside, Lang County, Linzhi City, Xizang Autonomous Region, China, is described herein based upon the integrative taxonomic results combining molecular phylogenetic systematics and morphological characteristic comparisons. Our molecular phylogeny was inferred by combining three mitochondrial gene fragments (//), and it indicated a distinct differentiation between the new species and species complex, with obvious genetic distances ( 9.9-11.

Microbial diversity in mountain-dwelling amphibians: The combined effects of host and climatic factors.

Comprehending the determinants of host-associated microbiota is pivotal in microbial ecology. Yet, the links between climatic factors and variations in host-associated microbiota necessitate further clarification. Mountain-dwelling amphibians, with limited dispersal abilities, serve as valuable models for addressing these questions.

A new Asian lazy toad of the genus Theobald, 1868 (Anura, Megophryidae) from southern Tibet, China.

In this study, a new species named is described from Luozha, southern Tibet, China. Genetic analysis based on two mitochondrial genes 16S rRNA and COI and the nuclear gene RAG1 revealed that the new species belongs to an independent phylogenetic clade close to and and shares no RAG1 haplotype with other species. Morphological comparisons based on examined specimens and literatures indicated that it can be diagnosed from congeners by the following combination of characters: (1) body moderate, male body length 47.

Study of Preoperative Antiviral Treatment of Patients with HCC Negative for HBV-DNA.

Aim: To study preoperative HBV-DNA negative HBV-related hepatocellular carcinoma (HCC) which was reactivated after surgery and could influence liver function and HCC recurrence.

Patients And Methods: Patients were divided into two groups according to preoperative antiviral therapy status. The control group comprised of 102 preoperative HBV-DNA-negative patients who had not undergone antiviral therapy before surgery.

Effects of Different Palliative Jaundice Reducing Methods on Immunologic Functions in Patients with Advanced Malignant Obstructive Jaundice.

Background/aim: This study aimed to investigate the effects of three treatment methods on the immunological function of patients with advanced malignant obstructive jaundice (MOJ).

Patients And Methods: Patients with advanced MOJ were randomly divided into three groups according to biliary drainage methods. Detection of levels of multi-indices were investigated in different time periods.

Partial Resection of the Pancreatic Head and Duodenum for Management of Carcinoma of the Ampulla of Vater: A Case Report.

A 57-year-old woman presented with spontaneous pain in the upper right quadrant of the abdominal region of one year's duration. Contrast-enhanced computed tomography (CT), magnetic resonance imaging, and magnetic resonance cholangiopancreaticography revealed the presence of a tumour in the periampullary region, gallstones, cholecystitis, and biliary obstruction, as well as atrophy of the pancreas and dense adhesions involving the pancreas, portal vein, and superior mesenteric vein. Duodenoscopy revealed a papillary neoplasm, measuring 2.

Cholangiocarcinoma: Present Status and Molecular Aspects of Diagnosis.

Cholangiocarcinomas are neoplasms that involve the epithelial cells of the bile duct, also known as cholangiocytes. This disease is difficult to diagnose early, as most symptoms present late in the disease. In addition, the specific anatomic position can cause periductal extension and result in a very low radical excision rate and a very poor prognosis.

Neurofibrosarcoma of the gallbladder: a case report.

Sarcoma of the gallbladder is a rare entity. This report presents an extremely rare clinical case of a neurofibrosarcoma of the gallbladder. On examination, a mass was felt in the right hypochondrium.
