Food-borne outbreak investigation currently relies on the time-consuming and challenging bacterial isolation from food, to be able to link food-derived strains to more easily obtained isolates from infected people. When no food isolate can be obtained, the source of the outbreak cannot be unambiguously determined. Shotgun metagenomics approaches applied to the food samples could circumvent this need for isolation from the suspected source, but require downstream strain-level data analysis to be able to accurately link to the human isolate. Until now, this approach has not yet been applied outside research settings to analyse real food-borne outbreak samples. In September 2019, a Salmonella outbreak occurred in a hotel school in Bruges, Belgium, affecting over 200 students and teachers. Following standard procedures, the Belgian National Reference Center for human salmonellosis and the National Reference Laboratory for Salmonella in food and feed used conventional analysis based on isolation, serotyping and MLe first Salmonella food-borne outbreak investigation uniquely linking the food source using a metagenomics approach and this in a fast time frame.As the representative multidrug-resistant pathogen, Stenotrophomonas maltophilia has multiple intrinsic and acquired resistances, including carbapenem resistance. In companion animals, the antimicrobial susceptibility and sequence types (STs) of S. maltophilia are not well understood due to its limited isolation rate. We investigated the antimicrobial susceptibilities and multilocus sequence types (MLSTs) of 38 S. maltophilia strains isolated from dogs and cats in Japan. Prevalence of resistance was detected for imipenem (100 %), aztreonam (94.7 %), piperacillin (65.8 %), trimethoprim-sulfamethoxazole (65.8 %), and ceftazidime (60.5 %). Rates of resistances to chloramphenicol, minocycline, and levofloxacin were low (2.6-5.3 %). MLST analysis revealed that all 38 strains were assigned to 34 STs, including 11 previously reported STs and 23 newly identified STs. Phylogenetic analysis of MLSTs enabled categorization of 13 isolates (34.2 %) into genogroup 6, which is a major genogroup of human isolates. Multinational surveillance would be needed to clarify the significance of antimicrobial-resistant S. maltophilia isolates from companion animals.
The pharmacological functions of
Wall. ex Lindl. (Orchidaceae) in cardiac hypertrophy remains unclear.

To evaluate whether
aqueous extract (DCAE) can attenuate experimental cardiac hypertrophy.

Cardiac hypertrophy in SD rats was induced by subcutaneously injection of isoproterenol (2 mg/kg), once a day for ten days. Rats were gavaged with DCAE (0.13 and 0.78 g/kg) daily for one month. find more At the end of treatment, measurement of left ventricular systolic pressure (LVSP), heart-to-body weight ratio (HW/BW), left ventricular/tibia length (LV/TL), atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) levels, haematoxylin-eosin staining, and Masson's trichrome staining were conducted. In cultured H9c2 cells, DCAE (2 mg/mL) and U0126 (10 μM) were added 2 h before the isoproterenol (10 μM) stimulus. Phalloidin staining was used to evaluate cellular hypertrophy. The mRNA expression of ANP and BNP was measured by qRT-PCR. The expression of p-ERK was determined by immunoblotting.

DCAE treatment significantly reduced the following indicators
(1) the LVSP (16%); (2) HW/BW (13%); (3) LV/TL (6%); (4) ANP (39%); (5) BNP (32%). In cultured H9c2 cells, phalloidin staining showed that DCAE relieved cellular hypertrophy (53% reduction). Furthermore, immunoblotting showed that DCAE can significantly inhibit p-ERK protein expression
(39% and 27% reduction, respectively).

DCAE prevents cardiac hypertrophy via ERK signalling pathway and has the potential for treatment of cardiac hypertrophy.

Zuogui Wan is a classic traditional Chinese prescription. Preliminary studies have confirmed that it could improve sperm quality significantly.

To investigate the effect of Zuogui Wan on testis structure and c-kitproto-oncogeneprotein (c-Kit) and octamer-binding transcription factor-4 (Oct4) expression in a rat model of impaired spermatogenesis.

Thirty-six Sprague-Dawley (SD) rats were divided into Blank control,
glycosides (GTW) and Zuogui Wan groups (n = 12). GTW was used to generate models of impaired spermatogenesis. Then Zuogui Wan group was administered 6 g/kg/d of Zuogui Wan granules for 4 weeks. Changes in the pathological structure and ultrastructure were observed with optical microscope and transmission electron microscope. Expression of c-Kit and Oct4 were quantified by RT qPCR and Western blots.

Both the pathological damage and the damages in the ultrastructure of spermatogenic epithelium had improved in Zuogui Wan group. Compared with the GTW model group (0.47 ± 0.19; 0.38 ± 0.14), c-Kit and Oct4 protein expression increased in the Zuogui Wan group (0.75 ± 0.27; 0.65 ± 0.23). C-Kit and Oct4 mRNA expression increased in Zuogui Wan group (1.06 ± 0.16; 1.85 ± 1.04) compared to the GTW model group (0.66 ± 0.23; 0.46 ± 0.29).

Zuogui Wan is capable of restoring the damage to the testis structure and ultrastructure and regulates the expression of c-Kit and Oct4 at protein and mRNA levels, inhibiting apoptosis and promoting proliferation of spermatogenic cells.

All the enrolled patients were anti-tumor necrosis factor (anti-TNF) naiive. The primary endpoint was best-corrected visual acuity (BCVA) improvement, and the secondary endpoints were changes in macular thickness, vitreous haze grade, anterior chamber (AC) cell grade, prednisolone dose, and the incidence of adverse reactions.Results Forty-eight patients were enrolled in the study. After adalimumab use, visual acuity improved significantly (p-value˂.001); vitreous haze grade decreased (p-value˂.001), and AC cell grade improved (p-value = .002). Macular thickness decreased, but its change was not statistically significant (p-value = .1). Moreover, adalimumab showed a corticosteroid-sparing effect (p-value = .03).Conclusion Biosimilar adalimumab (CinnoRA®) is effective and well-tolerated in Behçet's uveitis.Introduction This case report describes an 8 year old boy unsuccessfully treated for years for Vernal Keratoconjunctivitis. Case report We report a VKC resistant to all types of treatment known in the literature, such as topical and oral corticosteroids, topical and oral cyclosporine, immunotherapy, and third generation anti-histamine eye drops, due to unknown HIV co-infection. During further laboratory tests, patient tested positive for HIV even though he did not present any clinical manifestation of HIV disease. Only after antiretroviral treatment was started the allergy symptoms completely regressed. Conclusion This case report suggests considering investigation of HIV infection in patients with refractory allergic conjunctivitis.Interaction between the SARS-COV-2 (2019 novel coronavirus) spike protein and ACE2 receptors expressed on cellular surfaces initialises viral attachment and consequent infection. Blocking this interaction shows promise for blocking or ameliorating the virus' pathological effects on the body. By contrast to work focusing on the coronavirus, which has significant potential diversity through possible accumulation of mutations during transmission, targeting the conserved ACE2 protein expressed on human cells offers an attractive alternative route to developing pharmacological prophylactics against viral invasion. In this study, we screened a virtual database of natural peptides in silico, with ACE2 as the target, and performed structural analyses of the interface region in the SARS-COV-2 RBD/ACE2 complex. These analyses have identified 15 potentially effective compounds. Analyses of ACE2/polypeptide interactions suggest that these peptides can block viral invasion of cells by stably binding in the ACE2 active site pocket. Molecular simulation results for Complestatin and Valinomycin indicate that they may share this mechanism. The discovery of this probable binding mechanism provides a frame of reference for further optimization, and design of high affinity ACE2 inhibitors that could serve as leads for production of drugs with preventive and therapeutic effects against SARS-COV-2.Communicated by Ramaswamy H. Sarma.After one year, the COVID-19 pandemic caused by SARS-CoV-2 is still the largest concern for the scientific community. Of the many recognized drug targets of SARS-CoV-2, the main protease is one of the most important target due to its function in viral replication. We conducted an in silico study with repurposing drugs of antibiotics class against virus protease and peptidase using AutoDock tool. The following significant binding energy interaction was observed with protease (PDB 6LU7) like piperacillin -7.25; tobramycin -9.20 and doxorubicin (Doxo) -10.04 kcal/mol and with peptidase (PDB 2GTB) piperacillin -7.08; tobramycin -8.54 and Doxo -9.89 kcal/mol. Furthermore, the interaction and stability behavior of the Doxo-protease and Doxo-peptidase complexes were analyzed for a 100-nanosecond (ns) time. Calculated RMSD values observed using molecular dynamics simulation (MDS) were found to be 0.15-0.25 nm, RMSF calculation per residues showed a value near 0.2 nm and Rg values remained approximately 2.25 nm. MM-PBSA analysis of total binding energy calculation of Doxo-protease and Doxo-peptidase complexes are found to be -148.692 and -105.367 kJ/mol, respectively. Moreover, amino acid residue ASP-197 showed the lowest contribution binding energy i.e. -18.1185 kJ/mol, and amino acid residue ASP-187 showed -17.0267 kJ/mol contribution energy. Thus, significant docking interaction and stable dynamicity of Doxo-protease complex with time was suggested that Doxo could be a choice to inhibit potentially the viral proteases that could prevent the entry inside the host cell to control the COVID-19 disease.Communicated by Ramaswamy H. Sarma.Confidence-accuracy characteristic (CAC) plots were developed for use in eyewitness identification experiments, and previous findings show that high confidence indicates high accuracy in all studies of adults with an unbiased lineup. We apply CAC plots to standard old/new recognition memory data by calculating response-based and item-based accuracy, one using false alarms and the other using misses. We use both methods to examine the confidence-accuracy relationship for both correct old responses (hits) and new responses (correct rejections). We reanalysed three sets of published data using these methods and show that the method chosen, as well as the relation of lures to targets, determines the confidence-accuracy relation. Using response-based accuracy for hits, high confidence yields quite high accuracy, and this is generally true with the other methods, especially when lures are unrelated to targets. However, when analyzing correct rejections, the relationship between confidence and accuracy is less pronounced.
