Gut microbiota diversity in a dung beetle (Catharsius molossus) across geographical variations and brood ball-mediated microbial transmission.

The dung beetle primarily feeds on the feces of herbivorous animals and play a crucial role in ecological processes like material cycles and soil improvement. This study aims to explore the diversity and composition of the gut microbiota of Catharsius molossus (a renowned dung beetle originating from China and introduced to multiple countries for its ecological value) and exploring whether these gut microbes are transmitted vertically across generations. Using 16S rRNA and ITS rRNA gene sequencing techniques, we described the diversity and composition of gut microbes in C.

Laryngeal paraganglioma: The analysis of misdiagnosed cases and literature review.

Laryngeal paraganglioma (LP) is an exceptionally rare neuroendocrine tumor, underscoring importance of accurate identification to preclude misdiagnoses. In this review, we presented two typical misdiagnosed LPs, and offered reviews of LP cases reported over the preceding decade and all documented misdiagnosed LP cases. Furthermore, we systematically investigated the underlying causes of misdiagnosis and elucidated key points for effective differentiation.

Epigallocatechin-3-gallate improves the quality of maternally aged oocytes.

The decline in female fertility as age advances is intricately linked to the diminished developmental potential of oocytes. Despite this challenge, the strategies available to enhance the quality of aged oocytes remain limited. Epigallocatechin-3-gallate (EGCG), characterised by its anti-inflammatory, antioxidant and tissue protective properties, holds promise as a candidate for improving the quality of maternally aged oocytes.

[Simulation of PM Concentration Based on Optimized Indexes of 2D/3D Urban Form].

It is well known that urban forms can affect the source distribution and diffusion process of air pollution; however, practical quantitative methods and models on alleviating urban air pollution by optimizing urban form indexes are lacking. Using Chang Sha city as an example, we quantitatively analyzed the PM concentration distribution in terms of 2D/3D urban form indexes (e.g.

miR-373 inhibits autophagy and further promotes apoptosis of cholangiocarcinoma cells by targeting ULK1.

Intrahepatic cholangiocarcinoma is a malignant tumor originating from intrahepatic bile ducts. Surgical therapy, radiotherapy, and chemotherapy are taken to treat this disease, but it is prone to recurrence and metastasis, with poor prognosis. Therefore, it is of great significance to explore new targets and molecular mechanisms for the development of cholangiocarcinoma cells.

Interfacial Effect of Oxygen-Doped Nanodiamond on CuO and Micropyramidal Silicon Heterostructures for Efficient Nonenzymatic Glucose Sensor.

Herein, the novel strategy of copper oxide (CuO) deposited oxygen-doped nitrogen incorporated nanodiamond (NOND)/Si pyramids (Pyr-Si) heterostructure is studied for high-performance nonenzymatic glucose sensor. The combined properties of surface-modified NOND/Pyr-Si induced by different growth durations (5 to 20 min) of CuO is envisioned to improve glucose sensitivity and stability. For comparison, the same methods and parameters were deposited on the plane silicon wafers.

The roles of autophagy and apoptosis in burn wound progression in rats.

Understanding the role of cell death in burn wound progression is crucial for giving appropriate diagnoses and designing therapy regimens for burn patients. A well-described and reliable "comb burns model" was employed to evaluate the roles of autophagy and apoptosis in burn wound progression at 2 h, 6 h, 12 h, 24 h, and 48 h post-burn in a rat model. Immunohistochemistry (IHC) results showed that autophagy was detectable in hair follicle epithelium at 2 h post-burn, peaked at 12 h post-burn, then declined.

[Observation on the fluid resuscitation and the change in blood sodium of severely burned patients in the early stage].

Objective: To study the necessary amount of fluid consisting of electrolyte and colloid, the ratio of electrolyte and colloid used, and the change of blood sodium during early resuscitation in severely burned patients.

Methods: Sixty-seven patients with total burn surface area (TBSA) equal to or over 70% and full-thickness area equal to or over 50%TBSA, hospitalized from March 2004 to March 2009, were resuscitated with fluid. The infusion amount of electrolyte, colloid, and water, and urinary output of patients at post injury hour (PIH) 24, 48, and 72 were analyzed retrospectively.

[Prevalence of dementia among rural elderly in Gushan township, Fuzhou].

Objective: To study the prevalence of dementia and its related risk factors in people aged 65 years and older in Gushan township.

Methods: People aged 65 years or older in 22 villages of Gushan township were screened, from July 2007 to November 2007. Face to face interview with mini-mental state examination, and followed by clinical assessment.

[VEGF, COX-2 and MVD in lesions of patients with condyloma acuminatum].

Objective: To determine the roles of vascular endothelial growth factor (VEGF) and cyclooxygenase-2 (COX-2) in the occurrence and development of condyloma acuminatum (CA).

Methods: The VEGF, COX-2, and microvascular density (MVD) in the lesions of 61 CA patients were detected with immunohistochemical SP method. Seventeen skin tissues from healthy men served as controls.

A method for purification and viral inactivation of human placenta hemoglobin.

For pilot-scale manufacturing of hemoglobin-based oxygen carrying drugs, we should get highly pure and viral inactivated hemoglobin (Hb) at high recovery. In our method, placenta hemoglobin (PHb) solutions were purified by heating in the presence of reducing agent and deoxygenating conditions so that heat-sensitive proteins were selectively precipitated and virus was inactivated. The optimum preparative condition resulted in highly purified PHb solution (>99% pure) with approximate 90% recovery and less than 2% of MetHb content, maintained oxygen carrying capacity, residual phospholipids less than 1 ppm, free of endotoxin, bacteria, type A&B antigens and virus.

[Effects of hsf1 genotype on the constitutive expression of alphaB-crystallin in mice myocardium].

Aim: Try to clarify the effects of HSF1 gene on the constitutively expressed alphaBC.

Methods: To investigate the levels of constitutively expressed alphaB-Crystallin (alphaBC) in hsf1 knockout (hsf1 -/-) and hsf1 wild type (hsf1 +/+) mice myocardium by Western blot and immunohistochemistry.

Results: The alphaBC levels in hsf1 -/- and hsf1 +/+ were 68.
