Kβ1 may be effective in the treatment of intestinal inflammatory conditions including inflammatory bowel disease.
Together, these data suggest that the development of therapeutic agents targeting AMPKβ1 may be effective in the treatment of intestinal inflammatory conditions including inflammatory bowel disease.Allyl isothiocyanate (AITC) induces stomatal closure accompanied by reactive oxygen species (ROS) production and glutathione (GSH) depletion in Arabidopsis thaliana. In this study, stomatal responses to three other isothiocyanates (ITCs), benzyl isothiocyanate (BITC), sulforaphane (SFN), and phenethyl isothiocyanate (PEITC), were investigated in A. thaliana. All these ITCs significantly induced stomatal closure, where PEITC and BITC were most effective. The selected ITCs also induced ROS accumulation, cytosolic alkalization, and GSH depletion in guard cells. Moreover, all ITCs increased the frequency of cytosolic free calcium ([Ca2+]cyt) spikes (transient elevation), while PEITC and BITC showed the highest frequency. There was a strong positive correlation between the number of [Ca2+]cyt spikes per guard cell and the decrease in stomatal aperture. Both cytosolic alkalization and GSH content have a positive correlation with the decrease in stomatal aperture, but ROS production did not have a significant correlation with the decrease in stomatal apertures. These results indicate that the molecules with a functional ITC group induce stomatal closure that is accompanied by GSH depletion, cytosolic alkalization, [Ca2+]cyt spikes, and ROS production, and that the former three cellular events, rather than ROS production, are highly correlated with the decrease in stomatal aperture.There has been a recent upsurge in the interest about contraceptive development, evidenced by the Contraceptive Special Issue of Biology of Reproduction [1], with research funding from the Male Contraceptive Initiative and the Bill and Melinda Gates Foundation. Support from the Contraceptive Research Branch of the Eunice Kennedy Shriver National Institutes of Child Health and Human Development continues with a marked change in focus in the funding announcements. This has motivated me to reflect on research, mostly from my laboratory starting in the 1960s to the present, on the development of a male contraceptive based on the sperm-specific glycolytic enzyme, lactate dehydrogenase C (LDHC4). This review considers the rationale behind this research, the development paths pursued, obstacles encountered, and the renewed interest in going forward toward development of a male contraceptive mediated by the inhibition of the sperm-specific form of LDHC. I will address how some papers published many years ago are relevant to the present goals of non-hormonal contraception and will mention about innovative technology now available that can advance this project. This review presumably will serve as an instructive guide for a research program with a focused program related to contraception. As an aside, many of the citations in this review are to most of the 26 publications in Biology of Reproduction co-authored by this investigator and collaborators from 1974 through 2020 not long after the first issue of BOR which was published in April 1969.
The incidence and prevalence of inflammatory bowel diseases (IBD) in older adults are rising. There is a limited comparative assessment of risk of disease- and treatment-related complications in older patients (older than 60 years) with adult-onset (age at disease onset, 18-59 years; AO-IBD) vs elderly-onset IBD (age at disease onset, older than 60 years; EO-IBD). We compared clinical outcomes in older patients with IBD with AO-IBD vs EO-IBD.

We conducted a retrospective cohort study comparing risk of disease-related complications (IBD-related surgery, hospitalization, treatment escalation, clinical flare, or disease complication) and treatment-related complications (serious infection, malignancy, or death) in older patients with AO-IBD vs EO-IBD through Cox proportional hazard analysis, adjusting for age at cohort entry, disease phenotype, disease duration, prior surgery and/or hospitalization, medication use, disease activity at cohort entry, and comorbidities.

We included 356 older patients with IBD (AO-IBD, 191 patients, 67 ± 5 y at cohort entry; EO-IBD, 165 patients, 72 ± 8 y at cohort entry). No significant differences were observed in the risk of disease-related complications in older patients with prevalent vs incident IBD (adjusted hazard ratio [aHR], 0.85; 95% CI, 0.58-1.25), although risk of IBD-related surgery was lower in older patients with prevalent IBD (aHR, 0.47; 95% CI, 0.25-0.89). Older patients with prevalent IBD were significantly less likely to experience treatment-related complications (aHR, 0.58; 95% CI, 0.39-0.87).

Patients with AO-IBD have lower risk of treatment-related complications as they age compared with patients with EO-IBD, without a significant difference in risk of disease-related complications.

Coronavirus disease 2019 (COVID-19) virus is still spreading, finding out the initial hits of viral infection is important to minimize the mild/moderate population, prevent disease aggravation and organs dysfunction.ObjectiveWeinvestigated COVID-19 patients with different serum calcium levels.

We checkedthe serum calcium level of the patients based on days after symptom onsetas well asthe severity of COVID-19. We also checkeedmulti-organ injuries and immune cytokines level in their blood.

Both mild/moderate and severe critical cases we observedshowed low calciumlevelin the early stage of viral infection, while the severe/criticalcasesshowed significant lower calcium level than mild/moderatecases in the early stage. We also found that low calciumlevelrelated tosevere/criticalmulti-organ injuries especiallyin the mild/moderatepopulation. Proinflammatory cytokine IL-6 also correlated tocalcium changein both mild/moderateand severe/criticalcases.

Our finding indicates that calcium balance isaprimal hit of COVID-19 and a biomarker of clinical severity at the beginning of symptom onset.Calcium is closely associated with virus-associated multiple organ injuryesand the increase of inflammatory cytokines. Our results provide a new, important indicator of COVID-19 patients from mild/moderate to severe/critical serum calcium.

Autoimmune hepatitis (AIH) is a form of severe hepatitis that can recur after orthotopic liver transplant (OLT). Presentation of AIH in patients with OLT who do not have a history of AIH is called de novo AIH (DNAIH). We evaluated the clinicopathologic characteristics of AIH and DNAIH.

Clinicopathologic and outcome measures of 11 patients with recurrent AIH (RAIH) and 22 with DNAIH identified between 2000 and 2017 were compared.

Both cohorts showed female predominance. The mean clinical follow-up was 13 and 7.8 years in the in the RAIH and DNAIH groups, respectively (P = .1). Moderate portal inflammation was more common in patients with RAIH (64% vs 27%, P = .043). A trend was observed for more cases of DNAIH showing severe inflammation (36% vs 9%, P = .09) and submassive necrosis compared with RAIH (23% vs 0%, P = .086). A trend for more advanced fibrosis was also noted in the RAIH group (27% vs 5%, P = .059). Three patients with RAIH lost their grafts because of RAIH. Five-year disease-specific graft survival (GS) (P = .012) and overall GS (P = .015) were worse in patients with RAIH. Complement component 4d immunohistochemistry was positive in 2 patients with RAIH and 3 with DNAIH but showed no correlation with GS or other parameters.

RAIH seems to have a more aggressive clinical course than DNAIH and warrants closer clinical follow-up and aggressive treatment.

Natural products characterize a rich source of prospective chemical entities for the development of new effective drugs for neglected diseases. Scientific evaluation of medicinal plants has made it possible to use some metabolites from flavonoids and polyphenols compounds for the treatment of parasitic diseases. Therefore, we aimed in this study to evaluate the protective effect of Silver nanoparticles (Ag-NPs) biosynthesized using Fig and Olive extracts (NFO) against Cutaneous leishmaniasis in female Balb/c mice. A total of 70 mice were used and divided into seven groups. Treatment was initiated when local lesions were apparent, we found Fig and Olive extracts were found to be a good source for the synthesis of (Ag-NPs), their formation was confirmed by color change and stability in solution. Nanoparticles biosynthesized using Fig and Olive extracts induced a reduction in the average size of cutaneous leishmaniasis lesions compared with the untreated mice. Moreover, nanoparticles treatment decreased oxidative stress (LPO, NO), down regulation gene expression levels (TNF-α, IL-1β and BAX) and this antileishmanial activity of nanoparticles was associated with enhanced antioxidant enzyme activities. In addition, histopathological evaluation proved the antileishmanial activity of nanoparticles compared to the positive control. Therefore, we aimed in this study to evaluate the protective effect of silver nanoparticles biosynthesized using Fig and Olive extracts against cutaneous lesions induced by Leishmania major infection through their anti-inflammatory, antioxidant activities and faster clinical efficacy than standard pentavalent antimonial treatment.
Infliximab and adalimumab concentrations are associated with important outcomes in inflammatory bowel disease (IBD). Antibodies to infliximab (ATI) and adalimumab (ATA) are associated with reduced drug concentrations and worse outcomes. Because the efficacy of dose escalation to overcome antibodies is unclear, we assessed the impact of this strategy to overcome immunogenicity in IBD.

Infliximab and adalimumab dosing, drug, and antibody concentrations were extracted from a database of patients with IBD having specimens collected for therapeutic drug monitoring. The primary outcome compared proportions with either infliximab ≥5 μg/mL or adalimumab ≥7.5 μg/mL and undetectable antibodies between dose-escalated and non-escalated patients. Area under the receiver operating characteristic curve analyses determined antibody concentrations below which dose escalation was associated with the primary outcome.

The study included 63,176 patients treated with infliximab and 46,429 patients treated with adalimumab. We detected ATI and ATA in 23.
