Melatonin alleviates Hg toxicity by modulating redox homeostasis and the urea cycle in moss.

Mercury (Hg) is a highly toxic metal and can cause severe damage to many organisms under natural conditions. As an effective free radical scavenger and antioxidant, Melatonin (MT) has played important protective roles in alleviating oxidative damage caused by environmental cues including heavy metal stress in plants. However, the detailed mechanisms of melatonin in alleviating Hg toxicity still remain unclear in plants.

Effect of fucoidan on gut microbiota and its clinical efficacy in Helicobacter pylori eradication: A randomized controlled trial.

Objective: To assess the clinical efficacy of fucoidan-assisted standard quadruple therapy (SQT) in Helicobacter pylori (H. pylori) eradication and the improvement of gut microbiota.

Methods: An open-label randomized controlled trial was conducted at the Affiliated Hospital of Qingdao University in Shandong Province, China.

Diagnosis and treatment of gastric hamartomatous inverted polyp (GHIP) by endoscopic submucosal dissection: A case report.

Rationale: Gastric hamartomatous inverted polyps (GHIP) is not a common disease, and it has rarely been reported in the literature. Preoperative diagnosis is difficult due to the deep position and surface covered with normal gastric mucosa. However, with the progress of endoscopic technology, endoscopic submucosal dissection (ESD) can play a crucial role in the diagnosis and treatment of GHIP.

Different Photosynthetic Response to High Light in Four Triticeae Crops.

Photosynthetic capacity is usually affected by light intensity in the field. In this study, photosynthetic characteristics of four different Triticeae crops (wheat, triticale, barley, and highland barley) were investigated based on chlorophyll fluorescence and the level of photosynthetic proteins under high light. Compared with wheat, three cereals (triticale, barley, and highland barley) presented higher photochemical efficiency and heat dissipation under normal light and high light for 3 h, especially highland barley.

Effects of alendronate sodium combined with InterTan on osteoporotic femoral intertrochanteric fractures and fracture recurrence.

Background: Osteoporosis is a global disease affecting 6.6% of the total population. Osteoporosis complications include fractures, increased bone fragility, and reduced bone strength.

Esophageal stenosis after chemotherapy for breast cancer: A case report.

Rationale: Esophageal stenosis after chemotherapy in breast cancer patients is rare. Distinguishing esophageal stenosis from esophageal metastasis caused by breast cancer is important.

Patient Concerns And Diagnosis: A 62-year-old woman diagnosed with advanced breast cancer and no distant metastases gradually developed skin changes, oral ulcers and mucosal injures after four cycles of chemotherapy.

Acute Nitrite Exposure Induces Dysfunction and Oxidative Damage in Grass Carp Isolated Hemocytes.

To evaluate the effects of nitrite on the oxidative damage of blood cells of Grass Carp Ctenopharyngodon idella, the isolated hemocytes were exposed to nitrite (0, 1, 10, or 100 mg/L) for up to 24 h. Hemoglobin (Hb) and methemoglobin (MetHb) concentrations, reactive oxygen species (ROS) and malondialdehyde (MDA) levels, mitochondrial membrane potential (∆Ψm), and antioxidant enzyme activity were assayed to assess hematological parameters and the antioxidant defense mechanism. Results showed a remarkable decrease in Hb concentration with increasing nitrite concentration after a 24-h exposure, while the MetHb concentration increased significantly in nitrite exposure groups.

Laterally spreading tumor-like primary rectal mucosa-associated lymphoid tissue lymphoma: A case report.

Background: Colorectal mucosa-associated lymphoid tissue (MALT) lymphoma is a rare disease, and only a few cases have been reported to date. It has no specific clinical presentations and shows various endoscopic appearances. There is no uniform consensus on its treatment.

Lymphangiomatosis associated with protein losing enteropathy: A case report.

Background: Lymphangiomatosis is a multisystem disorder that is rarely localized to the gastrointestinal tract. Lymphangiomatosis usually has no specific clinical presentation and is easily misdiagnosed. A case report and review of the literature on lymphangiomatosis associated with protein-losing enteropathy will help to improve the overall understanding of this disease.

Early colon cancer with enteropathy-associated T-cell lymphoma involving the whole gastrointestinal tract: A case report.

Background: Enteropathy-associated T-cell lymphoma (EATL) is a rare invasive lymphoma derived from gastrointestinal epithelial T lymphocytes. EATL involving the whole gastrointestinal tract accompanied with early colon cancer is extremely rare.

Case Summary: We present the case of a 67-year-old man with diarrhea for more than 5 mo whose colonoscopy in another hospital showed multiple colonic polyps, which indicated moderate to severe dysplasia and focal early cancer.

Gastric adenocarcinoma of fundic gland type after eradication: A case report.

Background: Gastric adenocarcinoma of fundic gland type (GA-FG) has recently been proposed as a novel histological type of gastric cancer.

Case Summary: We report a case of GA-FG in a 77-year-old Chinese woman with epigastric distention who was referred to endoscopy for the management of an incidentally found submucosal tumor-like elevated lesion in the lower part of the gastric body. The tumor occurred after () eradication therapy without long-term use of proton pump inhibitors.

Production of vinegar using edible alcohol as feedstock through high efficient biotransformation by acetic acid bacteria.

In this paper, an optimal semi-continuous process for vinegar production from edible alcohol through biotransformation by acetic acid bacteria (AAB) WUST-01 was developed. The optimized medium composition for the starting-up stage was glucose 5.1 g/L, yeast extract 26.

Stevioside induced cytotoxicity in colon cancer cells via reactive oxygen species and mitogen-activated protein kinase signaling pathways-mediated apoptosis.

The role of mitogen-activated protein kinase (MAPK) signaling pathways in cell growth and differentiation has been well established. The present study aimed to investigate the anti-proliferative effect of stevioside on human colon cancer HT-29 cells. Additionally, the effect of stevioside on cell cycle arrest and MAPK signaling pathways in HT-29 cells was explored.

Cloning a novel endo-1,4-β-D-glucanase gene from Trichoderma virens and heterologous expression in E. coli.

Endo-1,4-β-D-glucanase (EG), as a key constituent of cellulase taking the responsibility of cutting β-1,4 glycosidic bonds, plays the essential role in the process of degrading cellulose by cellulase. Cloning and expressing the EG gene is important to the cellulase research and application. In this work, a novel EG gene was cloned from Trichoderma virens ZY-01, which was a cellulase secreting microbe isolated by our laboratory.

A Novel Cellulase Produced by a Newly Isolated Trichoderma virens.

Screening and obtaining a novel high activity cellulase and its producing microbe strain is the most important and essential way to improve the utilization of crop straw. In this paper, we devoted our efforts to isolating a novel microbe strain which could produce high activity cellulase. A novel strain ZY-01 was isolated from a cropland where straw is rich and decomposed, by using the soil dilution plate method with cellulose and Congo red.

Enzyme-linked immunosorbent assay for urinary aquaporin-2 water channel protein measurement.

Objective: To develop an efficient and stable enzyme-linked immunosorbent assay (ELISA) for detecting urinary aquaporin-2 (AQP2) water channel protein.

Methods: Rat AQP2 C-terminal peptides (CELHSPQSLPRGSKA) were synthesized and linked to KLH to prepare rabbit anti-AQP2 polyclonal antibodies, and IgG of the antibodies were labeled with horseradish peroxidase (HRP). Rat models of congestive heart failure (CHF) was established by ligation of the left coronary artery, in which both direct and sandwich ELISA for urinary AQP2 detection were tested.
