Interestingly, at a higher resolution, our results showed that spared nerve injury-induced neuropathic pain altered both the stability of the microbial community and the key microbes in a gut micro-ecosystem. Oscillospira, which was classified as a low-abundance and core microbe, was identified as the key microbe in the Sham group, whereas Staphylococcus, classified as a rare and non-core microbe, was identified as the key microbe in the spared nerve injury-induced neuropathic pain group.
In summary, our results provide novel experimental evidence that spared nerve injury-induced neuropathic pain reshapes gut microbial diversity, and alters the stability and key microbes in the gut.

Here we review our recent findings indicating that the gold-standard methods to assess PMS, including ACOG, induce a high degree of false-negative findings. We propose a new case definition of the menstrual cycle-associated syndrome (MCAS), which is characterized by increased DRSP scores during the menstrual cycle and by symptom increases the week prior to the menses. The MCAS case definition was externally validated by diverse biomarkers including plasma levels of progesterone and estradiol, chemokines (e.g. CCL2, CCL5 and CCL11), epidermal growth factor, hydroperoxides, paraoxonase 1 activity and complement C4. These biomarkers as well as IgA responses to Gram-negative bacteria are significantly associated with the DRSP and its subdomains including depression, anxiety, and physiosomatic (fatigue, pain) symptoms. In conclusion, we propose, to a) use the MCAS diagnosis as an indicant of menstrual cycle-related symptoms; and b) examine the associations of the time series in the DRSP and its subdomains and those in biomarkers including distributed lag models. Aberrations in the uterine-chemokine-brain-axis underpin the pathophysiology of MCAS whereby suboptimal pre-ovulatory follicular development coupled with a relative corpus luteum insufficiency may drive increased chemokine production, lowered antioxidant defenses, neuro-oxidative stress pathways, and increased bacterial translocation. As such, we have delineated new drug targets for the treatment of MCAS. This opinion paper reviews new possible treatments that should be trialed in MCAS.
NSAIDs are the most widely prescribed medications worldwide for their anti-inflammatory, antipyretic, and analgesic effects However, their chronic use can lead to several adverse drug events including GI toxicity. The selective COX-2 inhibitors developed as gastro-sparing NSAIDs also suffer from serious adverse effects which limit their efficacy.
Local generation of reactive oxygen species is implicated in NSAID-mediated gastric ulceration and their combination with H2 antagonists like famotidine reduces the risk of ulcers. The objective of this work was to design and synthesize novel methanesulphonamido isoxazole derivatives by hybridizing the structural features of NSAIDs with those of antiulcer drugs (ranitidine, famotidine, etc.) to utilize a dual combination of anti-inflammatory activity and reducing (antioxidant) potential.
The designing process utilized three dimensional similarity studies and utilized an isoxazole core having a potential for anti-inflammatory as well as radical scavenging antioxidant activity. The compounds were assayed for their antiinflammatory activity in established in vivo models. The in vitro antioxidant activity was assessed in potassium ferricyanide reducing power (PFRAP) assay employing ascorbic acid as the standard drug.
Compounds (5, 6, 9 and 10) showed anti-inflammatory activity comparable to the standard drugs and were also found to be non-ulcerogenic at the test doses. Compounds 6-10 exhibited good antioxidant effect in the concentration range of 1.0-50.0 µmol/ml. The test compounds were also found to comply with the Lipinski rule suggesting good oral absorption.
A new series of isoxazole based compounds is being reported with good anti-inflammatory activity coupled with antioxidant potential as gastro-sparing anti-inflammatory agents.

To propose the structural requirements of VGSC blockers through a quantitative structure-activity relationship analysis of drugs with proven activity.
IC50 values of anticonvulsant drugs on VGSCs were considered under similar experimental conditions; some physicochemical properties of the molecules that were correlated with their biological activity were determined in silico.
Relationships were found between the dipole moment, pKa, EHOMO, and MR with the biological activity, which infers that between greater polarity and basicity of the drugs, their activity as blockers will increase. Subsequently, the structural subclassification of the drugs was carried out, based on the urea derivation, the groups of which were Group 1 (direct and bioisoster derivatives) and Group 2 (homologue and vinylogue derivatives of urea).
The biological activity depends on the polarity, basicity, and electronic density of the drugs. The derivation of urea is essential, which is present in its original substituted form or a bioisosteric form. Urea can be in the form of a homologue or a vinylogue at the ends of the molecule. Aromatic substitution to the urea portion is necessary.

Over the years, transition metal complexes have exhibited significant antimicrobial and antitumor activity. It all started with cisplatin discovery, but due to the large number of side effects it shows, there is a growing need to find a new metal-based compound with higher selectivity and activity on more tumors.
Two novel trans-palladium(II) complexes with organoselenium compounds as ligands, [Pd(L1)2Cl2] (L1 = 5- (phenylselanylmethyl)-dihydrofuran-2(3H)-one) and [Pd(L2)2Cl2] (L2 = 2-methyl-5-(phenylselanylmethyl)- tetrahydrofuran) were synthesized, in the text referred to as Pd-Se1 and Pd-Se2. Also, a structurally similar trans-palladium(II) complex, [Pd(L3)2Cl2] (L3= 2,2-dimethyl-3-(phenylselanylmethyl)-tetrahydro-2H-pyran ) was synthesized according to an already published work and is referred to as Pd-Se3. The interaction of synthesized complexes with DNA and bovine serum albumin were done. Also, antimicrobial activity and in vitro testing, cell viability, and cytotoxic effects of synthesized ligandss shown on Pseudomo-nas aeruginosa. Under standardized laboratory conditions for in vitro testing, cell viability and cytotoxic effects of synthesized ligands and complexes were studied on human epithelial colorectal cancer cell line HCT-116, where Pd-Se2 showed some significant cytotoxic effects.
The newly synthesized complexes have the potential to be further investigated as metallodrugs.

However, there are still numerous challenges that need to be resolved before this gene delivery vehicle is used in clinical applications, such as the inability of AAV to effectively target specific tissues, preexisting neutralizing antibodies in human populations, and a limited AAV packaging capacity. Over the past two decades, much genetic modification work has been performed with the AAV capsid gene, resulting in a large number of variants with modified characteristics, rendering AAV a versatile vector for more efficient gene therapy applications for different genetic diseases.
Colon cancer is one of the most common cancer worldwide and has a poor prognosis. Through the analysis of transcriptome and clinical data of colon cancer, immune gene-set signature was identified by single sample enrichment analysis (ssGSEA) scoring to predict patient survival and discover new therapeutic targets.
To study the role of immune gene-set signature in colon cancer.
First, RNASeq and clinical follow-up information were downloaded from The Cancer Genome Atlas (TCGA). Immune gene-related gene sets were collected from ImmPort database. Genes and immunological pathways related to prognosis were screened in the training set and integrated for feature selection using random forest. Immune gene-related prognosis model was verified in the entire TCGA test set and GEO validation set and compared with immune cells scores and matrix score.
1650 prognostic genes and 13 immunological pathways were identified. These genes and pathways are closely related to the development of tumors. 13-immune gene-set signature was established, which is an independent prognostic factor for patients with colon cancer. Risk stratification of samples could be carried out in the training set, test set and external validation set. The AUC of five-year survival in the training set and validation set is greater than 0.6. Immunosuppression occurs in high-risk samples. Compared with published models, Riskscore has better prediction effect.
This study constructed 13-immune gene-set signature as a new prognostic marker to predict the survival of patients with colon cancer, and provided new diagnostic/prognostic biomarkers and therapeutic targets for colon cancer.

The article explores terminological and conceptual challenges and describes the empirical research literature in this field to date in relation to digital dating abuse, intimate partner cyberstalking, technology-facilitated sexual assault, image-based sexual abuse, and online sexual harassment. The article also discusses policy and practice responses to this growing problem, as well as future directions for research. We argue that research and practice need to be guided by existing conceptual frameworks that utilize gender and actor-network theory to understanding the causes and consequences of women's experiences of abuse and violence facilitated by digital technologies.
