Background/aim: Sex-related differences in response to pain have become a topic of increasing interest. However, sex-related differences in the efficacy of dexamethasone for postoperative analgesia have not been previously addressed. Materials and methods: The study included 196 men and 196 women, aged between 18 and 45 years, who were scheduled for laparoscopic cholecystectomy. The patients were randomly allocated into dexamethasone (M/F: 98/98) and control (normal saline; M/F: 98/98) groups. Patients in the study group received intravenous dexamethasone at 0...

Mammalian target of rapamycin (mTOR) is a central regulator of growth and metabolism. mTOR resides in two distinct multi-protein complexes - mTORC1 and mTORC2 - with distinct upstream regulators and downstream targets. While it is possible to specifically inhibit mTORC1 with rapamycin, or inhibit both mTOR complexes together with ATP pocket directed mTOR kinase inhibitors, it is not possible to assess the specific roles for mTORC2 pharmacologically. To overcome this, we have developed a novel, inducible, dominant negative system for disrupting substrate recruitment to mTORC2...

Rice (Oryza sativa L.) is a primary global food cereal. However, when compared to wheat, rice has poor food processing qualities. Dough that is made from rice flour has low viscoelasticity because rice seed lacks storage proteins that are comparable to gluten protein from wheat. Thus, current research efforts aim to improve rice flour processing qualities through the transgenic expression of viscoelastic proteins in rice seeds. In this study, we characterized the transgenic expression of wheat glutenin subunits in rice seeds...

Oral dryness is a common feature in menopausal women. Estrogen therapy can relieve this symptom; however, the underlying mechanism was not clear. Standardized isopropanolic black cohosh (Actaea racemosa; Remifemin) can also relieve menopausal symptoms, such as hot flashes and sweating. Our previous study showed that standardized isopropanolic black cohosh could protect the submandibular gland structure. To investigate the effects and possible mechanisms of action of estrogen and standardized isopropanolic black cohosh on submandibular gland function in ovariectomized (OVX) rats, we measured body weight, daily water consumption, and blood flow in the submandibular glands...

Insulin and leptin resistance are highly involved in metabolic syndrome and non-alcoholic fatty liver disease (NAFLD). Presently, no approved treatment is available. Actein is isolated from the rthizomes of Cimicifuga foetida, a triterpene glycoside, exhibiting important biological properties, such as anti-inflammatory, anti-cancer, and anti-oxidant activity. However, its effects on metabolic syndrome are poorly understood. The aims of the study were mainly to investigate the molecular mechanisms regulating insulin and leptin resistance, and lipogenic action of actein in high fat diet-fed mice...

BACKGROUND: Cyclophosphamide (CTX) is a widely used antitumor drug that can suppress the immune system. The effects of regulating immune response and antitumor of β-glucan from the cell wall of Candida albicans (CAIBG) have been confirmed. However, the effects of the combined use of CAIBG and CTX remain unclear and warrant further investigation. METHODS: S180 tumor-bearing models were developed for CAIBG (100 mg/10 mL/kg) and CTX (30 mg/10 mL/kg) intervention...

Estrogen deficiency following menopausal provokes alveolar bone loss, remodeling and inflammation. Eugenol is a phenolic compound with wide dental applications and anti-inflammatory properties. In the present study, the potential protective role of eugenol against alveolar bone deformities was investigated in an ovariectomized (OVX) rodent model. Two doses of eugenol (2.5 and 5 mg/kg/d) were administered to OVX animals for 12 weeks. In Serum, markers of bone metabolism and pro-inflammatory cytokines were estimated using ELISA...

Seizure is a neurological disorder including hippocampal oxidative and inflammatory stress, and glutamate toxicity. Thus, any agent(s) that mitigate(s) these events in hippocampus might attenuate seizure severity. The effects of asiatic acid (AA) or maslinic acid (MA) pre-administration at 20 or 40mg/kg body weight/day upon inflammatory, oxidative and apoptotic injury in hippocampus of kainic acid (KA)-treated mice were examined. KA induced seizure-like behavioral patterns, which was attenuated by AA or MA pre-administration...

REVIEW
Kevin D Hall, Scott Kahan
Weight loss can be achieved through a variety of modalities, but long-term maintenance of lost weight is much more challenging. Obesity interventions typically result in early weight loss followed by a weight plateau and progressive regain. This review describes current understanding of the biological, behavioral, and environmental factors driving this near-ubiquitous body weight trajectory and the implications for long-term weight management. Treatment of obesity requires ongoing clinical attention and weight maintenance-specific counseling to support sustainable healthful behaviors and positive weight regulation...

REVIEW
Katherine H Saunders, Devika Umashanker, Leon I Igel, Rekha B Kumar, Louis J Aronne
Although diet, physical activity, and behavioral modifications are the cornerstones of weight management, weight loss achieved by lifestyle modifications alone is often limited and difficult to maintain. Pharmacotherapy for obesity can be considered if patients have a body mass index (BMI) of 30 kg/m(2) or greater or BMI of 27 kg/m(2) or greater with weight-related comorbidities. The 6 most commonly used antiobesity medications are phentermine, orlistat, phentermine/topiramate extended release, lorcaserin, naltrexone sustained release (SR)/bupropion SR, and liraglutide 3...

Mallow (Malva sylvestris L.) has had medicinal and therapeutic uses in addition to its oral consumption. The present study was conducted to examine the protective effect of Malva sylvestris L. extract on ischemia-reperfusion-induced kidney injury and remote organ injuries in the liver. Before ischemia-reperfusion, rats in the different groups received intraperitoneal normal saline or mallow extract at the doses of 200, 400 or 600 mg/kg of body weight. After 30-minutes of bilateral renal ischemia followed by 24-hours of reperfusion, tissue damage in the kidney and liver samples were determined through studying H&E-stained slides under a light microscope...

Anorexia nervosa (AN) is a complex neuropsychiatric disorder presenting with dangerously low body weight, and a deep and persistent fear of gaining weight. To date, only one genome-wide significant locus associated with AN has been identified. We performed an exome-chip based genome-wide association studies (GWAS) in 2158 cases from nine populations of European origin and 15 485 ancestrally matched controls. Unlike previous studies, this GWAS also probed association in low-frequency and rare variants. Sixteen independent variants were taken forward for in silico and de novo replication (11 common and 5 rare)...

Chronic liver diseases, such as viral hepatitis, alcoholic liver disease, or non-alcoholic fatty liver disease, are characterized by continual inflammation, progressive destruction and regeneration of the hepatic parenchyma, liver progenitor cell proliferation, and fibrosis. The end-stage of every chronic liver disease is cirrhosis, a major risk factor for the development of hepatocellular carcinoma. To study processes regulating disease initiation, establishment, and progression, several animal models are used in laboratories...

Chimeric antigen receptor (CAR) T cells targeting CD19 mediate potent effects in relapsed and/or refractory pre-B cell acute lymphoblastic leukemia (B-ALL), but antigen loss is a frequent cause of resistance to CD19-targeted immunotherapy. CD22 is also expressed in most cases of B-ALL and is usually retained following CD19 loss. We report results from a phase 1 trial testing a new CD22-targeted CAR (CD22-CAR) in 21 children and adults, including 17 who were previously treated with CD19-directed immunotherapy...

In the present study we provide evidence that 3,3',5'-triiodothyronine (reverse T3, rT3) restores neurochemical parameters induced by congenital hypothyroidism in rat hippocampus. Congenital hypothyroidism was induced by adding 0.05% propylthiouracil in the drinking water from gestation day 8 and continually up to lactation day 15. In the in vivo rT3 exposure, hypothyroid 12-day old pups were daily injected with rT3 (50 ng/kg body weight) or saline until day 14. In the ex vivo rT3 treatment, hippocampal slices from 15-day-old hypothyroid pups were incubated for 30 min with or without rT3 (1 nM)...
