A real-time LAMP-based dual-sample microfluidic nick for speedy and also parallel recognition associated with a number of waterborne pathogenic germs through coast marine environments.
Intercellular lipids in the stratum corneum (SC), such as ceramide (CER), free fatty acid (FFA), and cholesterol (CHOL), contribute to the formation of stable lamellar structures in the SC, making them important for skin barrier function. β-Galactosylceramide (GalCer) is a glycosphingolipid that is used in some cosmetics and quasi-drugs in anticipation of a moisturizing effect. GalCer promotes keratinocyte differentiation and increases CER production by increasing β-glucocerebrosidase (β-GCase) activity. However, few reports have described the mechanism of these effects, and detailed studies on the role of GalCer in intercellular lipid production in the SC have not been conducted. This study investigated the effect of GalCer on the metabolism and production of intercellular lipids in the SC in a three-dimensional cultured epidermis model. After reacting GalCer with a homogenate solution of three-dimensional cultured epidermis, GalCer was hardly metabolized. Treatment of the three-dimensional cultured epidermis with GalCer increased the expression of genes involved in the β-GCase metabolic pathway and promoted CER production. In addition, GalCer treatment reduced the expression of FFA metabolism-related genes as well as palmitic acid levels. In addition, transepidermal water loss, which is a barrier index, was reduced by GalCer treatment. These findings suggested that GalCer, which is hardly metabolized, affects the production of intercellular lipids in the SC and improves skin barrier function.Moisturizing compounds are commonly applied topically to human stratum corneum (SC). Many types of molecular species are employed, most commonly including humectants and occlusives. We find new evidence of keratin dispersion caused by the moisturizing compound ectoine (1,4,5,6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid), and provide the first characterization of its impacts on the hydration kinetics and biomechanics of SC. A second compound, 2-(2-hydroxyethoxy)ethylguanidine succinate (HEG) was investigated for comparison. A suite of biomechanical and biochemical assays including FTIR, drying stress, and cellular cohesion were used. Studies were conducted on normal, lipid-extracted, and lipid plus natural moisturizing factor extracted SC. Ectoine was found to improve the dispersity and hydration of keratin bundles in corneocytes. It also decreased rates of stress development in lipid extracted SC when exposed to a dry environment by ∼30% while improving stress reduction during rehydration by ∼20%. Peak stresses were increased in harsh drying environments of less then 5% RH, but SC swelling measurements suggest that water retention was improved in ambient conditions. Further, changes up to ∼4 J/m2 were seen in cohesion after ectoine treatments, suggesting corneodesmosome interactions. HEG was tested and found to disperse keratin without impacting corneodesmosomes. These results indicate that keratin dispersants produce beneficial effects on SC hydration kinetics, ultimately resulting in higher SC hydration under ambient conditions.JAK/STAT plays an important role in cytokine signal transduction and it is potentially involved in the proinflammatory response during the early phase of severe acute pancreatitis (SAP). However, whether JAK2 activity is upregulated and whether JAK2 inhibition plays a role in the maintenance of pancreatic homeostasis during SAP is incompletely understood. Here we show that JAK2/STAT3 activity is highly elevated in SAP and blockade of JAK2 by AG-490 protects against SAP-induced pancreatic inflammation and injury. Gene expression and ELISA studies showed that JAK2 inhibition altered the cytokine profiles in both the circulation and pancreases. Further analysis revealed that JAK2 inhibition restored the level of cytokines critical for macrophage polarization towards M2 macrophage. Our findings suggest that pharmacological targeting at JAK2/STAT signalling may be an effective choice of therapeutic interventions against SAP.Macrolide-based combination chemotherapy is recommended for the treatment of Mycobacterium avium complex (MAC) pulmonary disease (MPD). The susceptibility of the MAC to macrolide antibiotics (MAs) determines the efficacy of treatment and clinical course of MPD. However, MAs cause several adverse effects, resulting in the discontinuation of macrolide-based combination chemotherapy. We encountered two women aged 65 years and 66 years diagnosed with MPD based on bronchoscopic examinations. They were initially treated with clarithromycin-based combination chemotherapy. However, neither patient could continue with chemotherapy owing to adverse events such as rash and edema. We switched clarithromycin with azithromycin, and the patients were able to continue chemotherapy without adverse events. Both patients completed their treatment successfully. Azithromycin, which also belongs to the class of MAs, can be a promising therapeutic option for MPD in case of clarithromycin intolerance.Salmonella typhi remains an endemic disease in Madagascar. Acute pancreatitis remains a rare complication of S. typhi colitis. We presented the case of a 27-year-old male, admitted to febrile diarrhea, vomiting, and severe abdominal pain. Blood work-up revealed elevated plasma lipase level. Abdominal CT scan showed acute pancreatitis without necrosis. Blood and stool culture positivity for S. typhi. Patient was diagnosed as acute pancreatitis caused by S. typhi. selleck chemicals llc The outcome was favorable under symptomatic medical treatment (rehydration and analgesic) combined with adapted antibiotic therapy. Acute pancreatitis is a possible complication of Salmonella infections. The presence of severe abdominal pain and febrile diarrhea should draw clinicians' attention to possible Salmonella acute pancreatitis.McKittrick-Wheelock syndrome (MWS) is a rare entity that has been described as electrolyte and fluid depletion secondary to secretory diarrhea caused by a large villous tumor in the colon or rectum. Most tumors associated with MWS are large but benign villous adenomas. Advanced cancers are seldom reported. We report a rare case of advanced rectal cancer with multiple liver and bone metastases presenting with MWS. A 59-year-old man was admitted to our hospital with a more than 3-year history of chronic mucous diarrhea. Laboratory data revealed hyponatremia, hypokalemia, hypochloremia, and renal failure. Based on the findings on colonoscopy, computed tomography, and magnetic resonance imaging, he was diagnosed with advanced rectal cancer with liver and bone metastases, and MWS. Following intravenous fluid treatment, abdominoperineal resection of the rectum with lymph node dissection was performed. The surgically resected specimen was a circumferential villous tumor measuring 110 × 80 mm. Histological examination of the resected specimens revealed signet ring cell carcinoma with villous adenoma and metastasis in regional lymph nodes. The renal dysfunction and electrolyte abnormalities that were present before surgery improved. Two courses of capecitabine were administered as adjuvant chemotherapy after the surgery. However, approximately 2 months after surgery, he died of poor general condition due to progression of the liver metastases.Fecal microbiota transplantation (FMT) is effective for induction of remission in ulcerative colitis (UC). Diet has potential to augment the efficacy and durability of FMT by encouraging engraftment of transplanted microorganisms. A trial of FMT combined with a defined diet was undertaken as salvage therapy for a 71-year-old woman with active steroid-refractory extensive UC. A multidimensional sulfide-reducing diet (4-SURE diet) was commenced followed by single-donor FMT administered by colonoscopy and then enemas over 7 days. Dietary adherence, clinical evaluation, and stool samples for metagenomic profiling were undertaken at weeks 0, 4, 8, and 24. Colonoscopy was performed 8 weeks post-FMT. Shotgun metagenomic profiling of the donor fecal suspension was also performed. A rapid clinical response to FMT and 4-SURE diet was observed with normalization of stool frequency (≤2 motions/day) and resolution of rectal bleeding within 2 weeks. Dietary adherence was excellent. Colonoscopy at week 8 revealed no evidence of active colitis (Mayo endoscopic sub-score 0) with histology showing no evidence of acute or chronic lamina propria inflammatory cell infiltrate. Sustained clinical and endoscopic remission out to 24 weeks was observed. Metagenomic sequencing confirmed sustained engraftment of beneficial donor microbiota with increased alpha-diversity and capacity for short-chain fatty acid production, including Faecalibacterium prauznitzii and Eubacterium hallii. This case report supports the rationale of prescribed diet therapy to support engraftment of donor microbiota following FMT for UC. Further large trials with a diet-arm control group are needed to evaluate FMT augmented by a defined diet in UC.The clover sign is a useful and characteristic radiological feature for diagnosing Crohn's disease with enteroenteric fistulae.
Fine-needle biopsy (FNB) needles obtain more core samples and support the shift from cytologic to histologic evaluation; however, recent studies have proposed a superior diagnostic potential for liquid-based cytology (LBC). This study compared the diagnostic ability of endoscopic ultrasound (EUS)-guided FNB histology with a 22-gauge Franseen needle (22G-FNB-H) and fine-needle aspiration (FNA) LBC with a conventional 25-gauge needle (25G-FNA-LBC).

We analyzed 46 patients who underwent both 22G-FNB-H and 25G-FNA-LBC in the same lesion during the same endoscopic procedure. This study evaluated the diagnostic ability of each needle, diagnostic concordance between needles, and incremental diagnostic effect of both needles compared to using each needle alone.

The agreement rate for malignancy between both techniques was 93.5% (kappa value = 0.82). There was no significant difference in the diagnostic ability of both methods. 22G-FNB-H and 25G-FNA-LBC provided an incremental diagnostic accuracy in two (4.3%) cases and one (2.2%) case, respectively.

Our study demonstrated that the diagnostic accuracy of 25G-FNA-LBC and 22G-FNA-H for solid pancreatic lesions were comparable. A conventional 25-gauge needle that punctures lesions with ease can be used in difficult cases and according to the skill of the endoscopist.

Administration of tenofovir alafenamide (TAF) as prevention or treatment of hepatitis B virus (HBV) reactivation is not well known. The aim of this study is to reveal the efficacy and safety of TAF against HBV reactivation.

Entecavir (ETV) and TAF were given to 66 and 11 patients, respectively, as prophylaxis against or treatment of HBV reactivation during chemotherapy or immune suppression therapy from January 2010 to June 2020. The antiviral effects and safety were assessed.

At week 24, the antiviral effects on patients receiving ETV and TAF were similar in terms of reduction of HBV DNA (-2.83 ± 1.45log IU/mL
-3.05 ± 2.47log IU/mL;
=0.857) and achieving undetectable levels of HBV DNA (78.8
90.9%;
=0.681). There was no significant difference in the decrease in the estimated glomerular filtration rate (eGFR) between the two groups (-0.62 ± 11.2mL/min/1.73 m

-3.67 ± 13.2mL/min/1.73 m
;
=0.291).
