This could save time and resources by reducing experimental work. In this review, we provide an overview of different theoretical models used to characterize imbibition in paper substrates and document the latest flow control strategies that have been applied to automated fluid control on paper. Additionally, we look at current efforts to commercialize paper-based devices along with challenges facing this industry.The outbreak of COVID-19 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been challenging human health worldwide. Loop-mediated isothermal amplification (LAMP) has been promptly applied to the detection of SARS-CoV-2 owing to its high amplification efficacy and less requirement of the thermal cycler. However, the vast majority of these LAMP-based assays depend on the non-specific detection of LAMP products, which can not discern the undesirable amplificons, likely to yield unreliable results. JNK Inhibitor VIII ic50 Herein, a sequence-specific LAMP assay was reported to detect SARS-CoV-2 using proofreading enzyme-mediated probe cleavage (named Proofman), which could realize real-time and visual detection without uncapping. This assay, introducing a proofreading enzyme and the fluorogenic probe to reverse-transcription LAMP (RT-Proofman-LAMP), can specifically detect the SARS-CoV-2 RNA with a detection limit of 100 copies. In addition to the real-time analysis, the assay is capable of endpoint visualization under a transilluminator within 50 min, providing a convenient reporting manner under the setting of point-of-care testing (POCT). In combination with different fluorophores, the one-pot multiplex assay was successfully achieved to detect multiple targets of SARS-CoV-2 and inner control simultaneously. In summary, the development of RT-Proofman-LAMP offers a versatile and highly-specific method for fast field screening and laboratory testing of SARS-CoV-2, making it a promising platform in COVID-19 diagnosis.Skin and soft tissue infections, such as cellulitis, are commonly diagnosed in the emergency department and these patients are often admitted to the hospital for intravenous antibiotic therapy. Oritavancin is a novel antibiotic approved for the treatment of skin and soft tissue infections that is administered as a one-time infusion. While oritavancin has demonstrated comparable efficacy with multi-dose parenteral antibiotics in clinical trials and has been proposed as an alternative to admission for emergency department patients, there is a paucity of available real world effectiveness data. In this case series, we describe the characteristics and outcomes of ten patients with high-risk skin and soft tissue infections who received oritavancin and were discharged from the emergency department.
Our previous clinical research showed that the interaction between gut microbiota and bile acids (BAs) in patients with type 2 diabetes mellitus (T2DM) changed significantly. We hypothesized that T2DM could be improved by adjusting this interaction mediated by farnesoid X receptor (FXR). T2DM belongs to the category of "xiaoke" in traditional Chinese medicine. Radix scutellariae has the effects of clearing away heat and eliminating dampness, curing jaundice and quenching thirst and is widely used alone or in combination with other medicines for the treatment of T2DM in China and throughout Asia. Additionally, the interaction between Radix scutellariae and gut microbiota may influence its efficacy in the treatment of T2DM.

This study chose Radix scutellariae to validate that T2DM could improve by adjusting the interaction between gut microbiota and bile acid metabolism.

Radix scutellariae water extract (WESB) was administered to a T2DM rat model established by a high-fat diet combined with streptozotocinintestine rather than the liver.

This study provided new ideas for the prevention or treatment of clinical diabetes and its complications by adjusting the interaction between gut microbiota and bile acid metabolism.

Bufei Yishen formula (BYF), a traditional Chinese medicine (TCM), is an effective therapeutic strategy for patients with chronic obstructive pulmonary disease (COPD).

To evaluate the efficacy of BYF and investigate its therapeutic mechanisms.

A total of 134 patients completed the study 68 patients treated by BYF combined with conventional Western medicine in the trial group; and 66 patients treated using conventional Western medicine in the control group. The efficacy of BYF was evaluated by a subgroup analysis of data obtained from a four-center, open-label, randomized controlled trial of comprehensive TCM interventions. A rat model of COPD was treated with the key active molecules (KAM) of BYF for 8 weeks. An in vitro model of COPD was also treated with KAM.

Patients treated with BYF had reduced frequency of acute exacerbation of COPD (p < 0.001) and duration (p = 0.028), dyspnea scale (p = 0.007), 6-min walking distance (p = 0.048). There were no differences observed in forced vital capacity in one second (FVC), forced expiratory volume in one second (FEV1), and FEV1 percentage of the predicted value (FEV1%). The five KAM of BYF (KAM-BYF) improved lung function, including tidal volume, minute ventilation, peak expiratory flow, FVC, FEV0.1, and FEV0.3, and pathological changes in COPD rats. Treatment with KAM-BYF markedly decreased the levels of interleukin 6 (IL6), tumor necrosis factor-α (TNF-α), matrix metalloproteinase 9 (MMP9), and MMP12 in serum and bronchial alveolar lavage fluid. In airway epithelial cells, KAM-BYF decreased the levels of TNF-α-induced IL8 and IL6. Finally, we discovered that the anti-inflammatory effects of KAM-BYF in COPD rats and BEAS-2Bs were mediated through inhibition of nuclear factor-kappaB (NF-κB) p65, c-Jun NH2-terminal kinase (JNK), and p38 mitogen-activated protein kinase signaling.

BYF exerts beneficial effects in patients with COPD via inhibition of inflammation.

However, the effect of platelet transfusion remains controversial for the lack of agreement on transfusion strategies. Before being transfused, platelets are stored in blood banks, and their activation is usually stimulated. Increasing evidence shows activated platelets may promote metastasis and the proliferation of cancer cells, while cancer cells also induce platelet activation. Such a vicious cycle of interaction between activated platelets and cancer cells is harmful for the prognosis of cancer patients, which results in an increased tumor recurrence rate and decreased five-year survival rate. Therefore, it is important to explore platelet transfusion strategies, summarize mechanisms of interaction between platelets and tumor cells, and carefully evaluate the pros and cons of platelet transfusion for better treatment and prognosis for patients with cancer with secondary thrombocytopenia.Dietary intake of long-chain, highly unsaturated ω-3 fatty acids (FAs) is considered indispensable for humans. The ω-3 FAs have been known to be anti-inflammatory and immunomodulatory dietary factors; however, the modes of action on pathogen recognition receptors (PRRs) and downstream signaling pathways have not been fully elucidated. Dietary sources contain various amounts of ω-3 long-chain fatty acids (LCFAs) of different lengths and the association between intake of these polyunsaturated fatty acids (PUFAs) with underlying mechanisms of various immune-related disorders can be of great interest. The potential anti-inflammatory role for ω-3 LCFAs can be explained by modification of lipid rafts, modulation of inflammatory mediators such as cytokines and PRRs. Toll-like receptors (TLRs) are a group of PRRs that play an important role in the recognition of bacterial infections and ω-3 FAs have been implicated in the modulation of downstream signaling of TLR-4, an important receptor for recognition of gram-negative bacteria. The ω-3 FAs docosahexaenoic acid and eicosapentaenoic acid have been investigated in vivo and in vitro for their effects on the nuclear factor-κB activation pathway. Identification of the effects of ω-3 FAs on other key molecular factors like prostaglandins and leukotrienes and their signals may help the recognition and development of medicines to suppress the main mediators and turn on the expression of anti-inflammatory cytokines and nuclear receptors.
The aim of this study was to compare the effects of muscle wasting according to measures obtained by different limb muscle mass indexes, to find the best mortality predictor among outpatients with cirrhosis.

Patients with liver cirrhosis (N=210) were submitted to dual-energy x-ray absorptiometry (DXA). Appendicular muscle mass (AMM), AMM index (AMMI), upper limb muscle mass (ULMM), and ULMM index (ULMMI) were calculated. The Model for End-Stage Liver Disease, anthropometric measures, and the presence of ascites and edema were also registered. Multiple logistic regressions were performed to determine mortality predictors; the area under the receiver operating characteristic curve was used to establish the best cutoff point to predict mortality.

The mean follow-up duration was 49 ± 15.59 mo. ULMM and ULMMI were clearly associated with mortality (P=0.007 and 0.001, respectively), whereas AMM and AMMI were not. After calculating the cutoff points for men and women, the presence of a depleted ULMMI as a categorical variable was associated with a mortality risk 2.5 times higher.

The results suggest that using ULMMI is better than AMMI for predicting mortality of outpatients with cirrhosis, thus offering a better measure to detect muscle wasting in this population using DXA.

Supplementing diet with citrulline has proved an efficient means of preserving nitrogen balance and improving nutritional status after massive intestinal resection. The aim of this study was to model the action of citrulline in gut-resected rats using a dose-ranging study focused on skeletal muscle nitrogen homeostasis.

Forty-six rats were randomly assigned to one of the following groups citrulline 0.5 g·kg·d
(n=9), citrulline 1 g·kg·d
(n=7), citrulline 2.5 g·kg·d
(n=8), citrulline 5 g·kg·d
(n=8), control (n=6), and sham (n=8). The sham group underwent transection and the other groups underwent resection of 80% of the small intestine. All rats were then fed enteral nutrition (EN; all diets were isocaloric and isonitrogenous). After 10 d, the rats were sacrificed to measure and analyze animal weight; duodenum, jejunum, and ileum weight; and muscle trophicity. Protein fractional synthesis rate (FSR) and mammalian target of rapamycin complex (mTORC)1 activation were measured in the tibialis muscle.

There was a significant dose-dependent association between rat weight and citrulline dose up to 2.
