Furthermore, the apoptosis rate increased significantly from 6.03% in the control group to 38.35% in Saos-2 cells that were treated with the combination of MTX and Que.
Que, with the potential to boost the anticancer activity of MTX on Saos-2 cancer cells through proliferation inhibition and apoptosis induction, is a good candidate for combination therapy.

Osteosarcoma (OS) as the most frequent primary bone malignancy in children and adolescents has a short survival rate in advanced stages. Alternative herbal medicines with fewer side effects or the potency to protect common therapy's side effects can be helpful in combinational therapies. Herein, we aim to explore the effects of Thymoquinone (TQ) combined with Methotrexate (MTX) on Saos-2 cells apoptosis.
The effects of TQ and MTX alone or in combination on Saos-2 cell viability were measured by MTT assay. Real-time PCR was applied for the measurement of Bax, BCL-2, and caspase-9 mRNA expression. Apoptosis evaluation was conducted by flow cytometry.
TQ improves the cytotoxic effects of MTX on Saos-2 cells proliferation at lower doses. Indeed, the IC50 of MTX decreased from 26 μM to 15 μM when it combined with TQ. TQ and MTX can induce the expression level of pro-apoptotic factors, Bax and caspase-9 while inhibiting anti-apoptotic protein BCL-2. Moreover, the combination of TQ and MTX potentiates apoptosis to 73%, compared to either TQ (48%) or MTX (53%) treated cells.
The co-treatment of TQ and MTX is associated with the up-regulation of apoptotic factors and down-regulation of anti-apoptotic factors, conducting apoptosis aggravation and OS cell death.

Vaccination against tuberculosis is one of the most successful medical measures to reduce morbidity and mortality. The BCG vaccine has been in use for more than 100 years, but its efficacy is still controversial. New vaccine candidates may offer better protection than available BCG vaccine. In this work, we studied the acute and the repeated-dose toxicity study of a new vector vaccine TB/Flu-04L against tuberculosis.
The study was conducted on 60 BALB/c mice and 150 Wistar rats. The vaccine was administered intranasally and intravenously for the acute toxicity study. For the repeated-dose toxicity study, rats were intranasally immunized by 6.5 log

three times with 21-day intervals. Etomoxir Mortality, temperature, body weight, food and water consumption, hematological and biochemical parameters, urine analysis, as well as cardiovascular, respiratory, and central nervous system parameters were evaluated. A macroscopic examination of internal organs was performed.
The TB/FLU-04L vaccine did not cause death among the mice and rats in the acute toxicity study. There were no pathological abnormalities in animal condition, behavior, food and water consumption, temperature, and body weight during the observation period. The results suggest that intranasal repeated-dose administration of the TB/FLU-04L vaccine does not exhibit significant toxicity in rats.Hematological and biochemistry analysis and the histological examination identified no toxicity-associated changes.
The toxicity study in mice and rats showed that the intranasal vector vaccine TB/FLU-04L had no toxic effect. The tests confirm no adverse effects for laboratory animals in the studied parameters.

Orexin neuropeptides are implicated in physical dependence on opioids and expression of withdrawal symptoms in drug abuse. The paraventricular nucleus of the midline thalamus (PVT) has a high expression of orexin receptors. The current research studied the effect of orexin-A in the PVT area on the development of behavioral indices produced by morphine withdrawal in rats.
Male Wistar rats weighing 250-300 gr were utilised. To produce drug dependence, morphine (6, 16, 26, 36, 46, 56, and 66 mg/kg, 2 ml/kg) was injected at an interval of 24 hrs for 7 days. To assess the involvement of the orexin in withdrawal syndrome, we injected orexin-A (100 μM, 200 nl) into the PVT for 7 days before each morphine injection. On the day after the last injection of morphine, naloxone (2.5 mg/kg, i.p.) was injected to elicit the morphine withdrawal symptoms which were observed and checked for 25 min.
The results of the current research showed that the orexin-A in PVT enhances the severity of behavioral symptoms prompted by the injection of naloxone in drug-dependent rats.
These observations imply that targeting the orexin receptors in PVT might exhibit a new therapeutic strategy for the future treatment of dependence.

Current evidence now shows that this relationship is two-way, as psychosocial stress can cause skin disease and its worsening. This interrelationship poses a major challenge.
The importance of autoimmune encephalitis and its overlap with infectious encephalitides are not well investigated in South-East Asia.
We report autoantibody testing, using antigen-specific live cell-based assays, in a series of 134 patients (cerebrospinal fluid and sera) and 55 blood donor controls (sera), undergoing lumbar puncture for suspected meningoencephalitis admitted in Vientiane, Lao People's Democratic Republic (PDR).
Eight of 134 (6%) patients showed detectable serum neuronal autoantibodies, against the N-methyl-D-aspartate and gamma-aminobutyric acid A receptors (NMDAR and GABAAR), and contactin-associated protein-like 2 (CASPR2). Three of eight patients had accompanying autoantibodies in cerebrospinal fluid (two with NMDAR and one with GABAAR antibodies), and in two of these the clinical syndromes were typical of autoimmune encephalitis. Three of the other five patients had proven central nervous system infections, highlighting a complex overlap between diverse infectious and autoimmune causes of encephalitis. No patients in this cohort were treated with immunotherapy, and the outcomes were poor, with improvement observed in a single patient.
In Lao PDR, autoimmune encephalitis is underdiagnosed and has a poor prognosis. Empiric immunotherapy should be considered after treatable infectious aetiologies are considered unlikely. Awareness and diagnostic testing resources for autoimmune encephalitis should be enhanced in South-East Asia.

Lower physical activity (PA) is associated with greater perceived fatigability, a person-centered outcome. The association between change in PA and fatigability with advanced age has yet to be established.
Community-dwelling older men (N=1,113, age=84.1± 3.9 years at Year 14) had free-living PA assessed using SenseWear Armband prospectively at Year 7 (2007-2009) and Year 14 (2014-2016) of MrOS, a longitudinal cohort established in 2000 (baseline). We categorized percent changes in PA into groups (large decline → large increase) for four metrics step count, light intensity PA (LIPA, METs>1.5 - <3.0), moderate-to-vigorous PA (MVPA, METs≥3.0), and sedentary behavior (SB, METs≤1.5, excluding sleep). Perceived physical and mental fatigability were measured (Year14) with the Pittsburgh Fatigability Scale (PFS, higher score=greater fatigability; range=0-50). Associations between each metric of percent changes in PA and fatigability were examined using linear regression, adjusted for demographics, change in health conditions and Year 7 step count or total PA (METs>1.5).
Men declined 2336±2546 (34%) steps/day, 24±31 (25%) LIPA min/day, 33±58 (19%) MVPA min/day, and increased 40±107 (6%) SB min/day over 7.2±0.7 years. Compared to large decline (% change< -50%), those that maintained or increased step count had 3-8 points lower PFS Physical scores; those who maintained or increased LIPA and MVPA had 2-3 and 2-4 points lower PFS Physical scores, respectively (all p≤.01). Associations were similar, but smaller, for PFS Mental scores.
Older men who maintained or increased PA had lower fatigability, independent of initial PA. Our findings inform the types and doses of PA that should be targeted to reduce fatigability in older adults.

It would, however, also be fair to say that not enough is yet known about older adults and hence it is unclear if government programs truly address those needs. Nepal is a very poor country that is still largely rural and characterized by extremes of inequality based on caste/ethnicity, gender, region, and income/wealth. In this paper, we describe the demographic and social conditions of older adults in Nepal, inequality, sources, and limitations of the data about older adults, and public policy and programs for older adults. We believe that studies of older adults in Nepal would benefit from adopting social determinants of health, healthy aging, and life-course perspectives to both identify needs and formulate policy for older adults in Nepal.
The study objective was to evaluate 2- and 3-dose coronavirus disease 2019 (COVID-19) mRNA vaccine effectiveness (VE) in preventing COVID-19 hospitalization among adult solid organ transplant (SOT) recipients.
We conducted a 21-site case-control analysis of 10 425 adults hospitalized in March to December 2021. Cases were hospitalized with COVID-19; controls were hospitalized for an alternative diagnosis (severe acute respiratory syndrome coronavirus 2-negative). Participants were classified as follows SOT recipient (n = 440), other immunocompromising condition (n = 1684), or immunocompetent (n = 8301). The VE against COVID-19-associated hospitalization was calculated as 1-adjusted odds ratio of prior vaccination among cases compared with controls.
Among SOT recipients, VE was 29% (95% confidence interval [CI], -19% to 58%) for 2 doses and 77% (95% CI, 48% to 90%) for 3 doses. Among patients with other immunocompromising conditions, VE was 72% (95% CI, 64% to 79%) for 2 doses and 92% (95% CI, 85% to 95%) for 3 doses.
