Crassostrea gigas Thunberg and other oysters have been traditionally used in China as folk remedies to invigorate the kidney and as natural aphrodisiacs to combat male impotence.

Erectile dysfunction (ED) has become a major health problem for the global ageing population. The aim of this study is therefore to evaluate the effect of peptide-rich preparations from C. gigas oysters on ED and related conditions as increasing evidence suggests that peptides are important bioactive components of marine remedies and seafood.

Crassostrea oyster peptide (COP) preparations COP1, COP2 and COP3 were obtained from C. gigas oysters by trypsin, papain or sequential trypsin-papain digestion, respectively. The contents of testosterone, cyclic adenosine monophosphate (cAMP) and nitric oxide (NO) and the activity of nitric oxide synthase (NOS) in mice and/or cells were measured by enzyme-linked immunosorbent assays. Real-time PCR was used to assess the expression of genes associated with sex hormone secretion pathways. #link# Thhealth issues.

this website (KLT) is an active extract of the Coix lacryma-jobi seed, which can benefit Qi and nourish Yin, and disperse the accumulation of evils. It is used as a biphasic broad-spectrum anti-cancer drug, and shows synergistic effects with radiotherapy and chemotherapy. However, the mechanism of KLT combined with cisplatin (CDDP) against hepatocellular carcinoma (HCC) has not been elucidated.

The aim of present study was to investigate the potential synergistic effects of KLT and CDDP on HepG2 cells, discussing the possible mechanisms from the perspective of CKLF1 and NF-κB mediated inflammatory response and chemoresistance, and the involvement of drug efflux transporters.

CDDP injured HepG2 cells were used to investigate the effects of KLT on chemotherapeutics treated HCC. Effects of KLT pretreatment on CDDP injured HepG2 cells were determined by MTT, wound healing assay, and transwell assay. Expression of chemokine-like factor 1 (CKLF1) and activation of nuclear factor κB (NF-κB) were examined by qPCR,ich may contribute to inflammation of tumor microenvironment and chemoresistance of CDDP. Inhibition of transporter-mediated drug efflux is also involved in KLT mediated sensitization effects of CDDP.The reproductive toxicity of SnS2 nanoflowers (SnS2 NFs) has been studied in our previous experiment, but the underlying mechanism is still not clear. Astaxanthin (ASX) is a red carotenoid pigment with antioxidant, anticancer and anti-inflammatory properties, showing neuroprotective properties via its antioxidant capacity. To examine the ASX effect on sub-chronic testis injury induced by SnS2 NFs, we randomly and equally divided 40 Kunming male mice into four groups (control, ASX control, NF and NF + ASX groups). Then, ASX dissolved in olive oil was administered intragastrically for 30 consecutive days. Results showed that ASX treatment improved the sperm parameters in mice. Meanwhile, the ASX treatment significantly attenuated testis histopathological injury and ultrastructure alterations induced by SnS2 NFs. It also alleviated testicular oxidative stress, inflammation, apoptosis and necroptosis in mice. Furthermore, ASX markedly upregulated the expression of Bcl-2 and downregulated the expressions of Fas, FasL, RIPK1, FADD, Bax, Cytochrome C, Caspase-9, Cleaved Caspase-8, Cleaved Caspase-3, RIPK3, MLKL and FLIP in the testis tissues compared with the NF group. Therefore, ASX had a markedly protective effect against SnS2 NFs in mice, and the potential mechanism is associated with its ability to inhibit the oxidative stress, inflammatory response, testicular apoptosis and necroptosis, as well as downregulating in the expression of the RIPK1-RIPK3-MLKL signaling and mitochondrial related apoptosis genes.The existing information supports the use of this material as described in this safety assessment.2-Propanol, 1,1',1',1'-(1,2-ethanediyldinitrilo)tetrakis- was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from the target material and read-across analog 1,1',1-nitrilotripropan-2-ol (CAS # 122-20-3) show that 2-propanol, 1,1',1',1'-(1,2-ethanediyldinitrilo)tetrakis- is not expected to be genotoxic. Data on 2-propanol, 1,1',1',1'-(1,2-ethanediyldinitrilo)tetrakis- provide a calculated margin of exposure (MOE) >100 for the repeated dose toxicity and reproductive toxicity endpoints and show that there are no safety concerns for skin sensitization under the current declared levels of use. The phototoxicity/photoallergenicity endpoints were evaluated based on ultraviolet (UV) spectra; 2-propanol, 1,1',1',1'-(1,2-ethanediyldinitrilo)tetrakis- is not expected to be phototoxic/photoallergenic. The local respiratory toxicity endpoint was evaluated using the threshold of toxicological concern (TTC) for a Cramer Class III material, and the exposure to 2-propanol, 1,1',1',1'-(1,2-ethanediyldinitrilo)tetrakis- is below the TTC (0.47 mg/day). link2 The environmental endpoints were evaluated; 2-propanol, 1,1',1',1'-(1,2-ethanediyldinitrilo)tetrakis- was found not to be persistent, bioaccumulative, and toxic (PBT) as per the International Fragrance Association (IFRA) Environmental Standards, and its risk quotients, based on its current volume of use in Europe and North America (i.e., Predicted Environmental Concentration/Predicted No Effect Concentration [PEC/PNEC]), are less then 1.To explore the impact of Huangjinya on metabolic disorders and host endogenous metabolite profiles, high-fat diet (HFD)-fed mice were administrated with Huangjinya green tea extract (HGT) at the dose of 150 or 300 mg/kg for 9 weeks. Epigallocatechin gallate was the main catechin derivative, followed by epigallocatechin and catechin presented in HGT, which contained high levels of free amino acids (50.30 ± 0.60 mg/g). HGT significantly alleviated glucose and insulin intolerance, reduced hepatic lipid accumulation and liver steatosis, and prevented white adipose tissue expansion in HFD-fed mice. Untargeted mass spectrometry-based metabolomics analysis revealed that HGT reduced the abundance of fecal branched-chain amino acids, aromatic amino acids, sphingolipids, and most acyl cholines, modulated bile acid metabolism by increasing chenodeoxycholate and reducing cholic acid content, and increased unsaturated fatty acids content. Fatherly, HGT activated insulin/PI3K/Akt and AMPK signaling pathways in the liver, reduced adipogenic and lipogenic genes expression, and promoted the genes expression related to lipolysis and adipocyte browning in white adipose tissue, contributed to improving metabolic syndrome in HFD-fed mice. The current study reported the impact of HGT supplementation on endogenous metabolite profiles, and highlights the positive roles of HGT in preventing diet-induced obesity and the related metabolic disorders.

Extracorporeal cardiopulmonary resuscitation (ECPR) has been increasingly used for adult cardiac arrest (CA) patients refractory to conventional CPR. However, data on early prognosticators of neurological outcome are lacking.

CA patients undergoing ECPR were prospectively monitored via amplitude-integrated EEG (aEEG). Targeted temperature management (TTM) was induced using an extracorporeal membrane oxygenation system. aEEG background patterns were classified into continuous normal voltage (CNV), discontinuous normal voltage (DNV), low voltage (LV), flat trace (FT), burst suppression (BS), and status epilepticus (SE). The Cerebral Performance Category (CPC) scale scores at hospital discharge and at 6 months after discharge were assessed, as was wakefulness after TTM. Good neurological outcome was defined as a CPC score of 1 or 2.

Twenty-two patients were studied. Six patients who showed CNV within 24 hours after arrival, including one with initial FT and two with initial LV, regained consciousness and had good neurological outcome except for one who died of haemorrhagic complication. Patients with persistent FT or BS at any time did not regain consciousness. Regarding 19 patients in whom aEEG data were obtained within 24 hours, CNV background predicted good outcome at 6 months with 100% sensitivity, 93% specificity, 83% positive predictive values, and 100% negative predictive values. All these indices were 100% concerning wakefulness after TTM.

aEEG monitoring was feasible and practical in adult CA patients undergoing ECPR and TTM. Evolution of aEEG background within 24 hours provides early accurate information for neurological prognostication.

To identify the most accurate early warning score (EWS) for predicting an adverse outcome in COVID-19 patients admitted to the emergency department (ED).

In adult consecutive patients admitted (March 1-April 15, 2020) to the ED of a major referral centre for COVID-19, we retrospectively calculated NEWS, NEWS2, NEWS-C, MEWS, qSOFA, and REMS from physiological variables measured on arrival. Sensitivity, specificity, positive (PPV) and negative predictive value (NPV), and the area under the receiver operating characteristic (AUROC) curve of each EWS for predicting admission to the intensive care unit (ICU) and death at 48 h and 7 days were calculated.

We included 334 patients (119 [35.6%] females, median age 66 [54-78] years). At 7 days, the rates of ICU admission and death were 56/334 (17%) and 26/334 (7.8%), respectively. NEWS was the most accurate predictor of ICU admission within 7 days (AUROC 0.783 [95% CI, 0.735-0.826]; sensitivity 71.4 [57.8-82.7]%; NPV 93.1 [89.8-95.3]%), while REMS was the most accurate predictor of death within 7 days (AUROC 0.823 [0.778-0.863]; sensitivity 96.1 [80.4-99.9]%; NPV 99.4[96.2-99.9]%). Similar results were observed for ICU admission and death at 48 h. NEWS and REMS were as accurate as the triage system used in our ED. MEWS and qSOFA had the lowest overall accuracy for both outcomes.

In our single-centre cohort of COVID-19 patients, NEWS and REMS measured on ED arrival were the most sensitive predictors of 7-day ICU admission or death. link3 EWS could be useful to identify patients with low risk of clinical deterioration.

The global pandemic of coronavirus disease 2019 (COVID-19) has placed a huge strain on UK hospitals. Early studies suggest that patients can deteriorate quickly after admission to hospital. The aim of this study was to model changes in vital signs for patients hospitalised with COVID-19.

This was a retrospective observational study of adult patients with COVID-19 admitted to one acute hospital trust in the UK (CV) and a cohort of patients admitted to the same hospital between 2013-2017 with viral pneumonia (VI). The primary outcome was the start of continuous positive airway pressure/non-invasive positive pressure ventilation, ICU admission or death in hospital. We used non-linear mixed-effects models to compare changes in vital sign observations prior to the primary outcome. Using observations and FiO

measured at discharge in the VI cohort as the model of normality, we also combined individual vital signs into a single novelty score.

There were 497 cases of COVID-19, of whom 373 had been discharged from hospital.
