In primates and most domestic animals, these stages occur during fetal life and thus, are difficult to study. Our laboratory has used cattle, an excellent model for human ovarian development, to elucidate the regulation of these early stages in fetal bovine ovarian tissue in vitro. The experiments described here were designed to determine if fetal bovine ovaries have activin A and its receptors and if activin A affects follicular formation and/or activation to begin growth. During the second trimester, when follicles first form, activin increased the total number follicles and the number of primary (activated) follicles in cultured ovarian cortical pieces, compared to control medium; its effects were similar to the positive control, insulin. During the second trimester, activin decreased primordial follicle numbers and increased primary and secondary follicles, again mimicking the positive control. Our previous experiments showed that fetal ovaries produce ovarian steroids, particularly during the second trimester, and that estradiol and progesterone inhibit follicle formation and activation. In control and gonadotropin-treated ovarian pieces, activin A increased progesterone, but decreased androstenedione and estradiol accumulation in the medium. Messenger RNA for activin and its type II receptors was detected in fetal bovine ovaries, with ACVR2A receptor mRNA more abundant than ACVR2B. Immunohistochemistry localized mRNA for activin A and ACVR2A to germ cells of all stages, granulosa cells, and theca cells of early secondary follicles. Staining for ACVR2B was weaker and mostly confined to germ calls. Taken together, these results strongly suggest that activin A of fetal ovarian origin 3 plays a role in ovarian development by promoting follicle formation and activation and modulating ovarian steroidogenesis.","PeriodicalId":94137,"journal":{"name":"Medical research archives","volume":"343 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76401540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A simple acute ischemic stroke scale (AISS) of the cortical representations of the anterior circulation can rapidly predict LVO, saving precious time to initiate early intravenous tissue plasminogen activator and endovascular mechanical thrombectomy. We proposed an ASIS in the emergency department called Gaze Weakness Neglect Speech (GWNS) to evaluate its feasibility and predictability for the detection of LVO in anterior circulation in the emergency department. Additionally, to evaluate if time can be gained that has been lost in obtaining National Institute of Health stroke Scale (NIHSS) and computed tomographic angiography (CTA), avoiding unnecessary radiation. Methods: This is a prospective observational study. An institutional review board permission was obtained, and patient enrollment started in January 2020 and ended in January 2021. Consecutive patients from January 2020 to September 2021 were selected from the database. The GWNS stroke scale was used by stroke and vascular neurologist during the emergency triage. The GWNS stroke scale scores range from 0 to 4 (1 for positive 0 for negative). The GWNS stroke scale assesses gaze deviation or gaze preference (G), presence of any weakness (W), neglect/disregard (N), and any speech impairment (S). Demographic data, CTA/cerebral angiographic data, and scores from NIHSS were also collected. The collected data was analyzed by a biostatistician to determine the association between the GWNS scale score and LVO. Results: In our study,109 qualifying patients were selected. Fifty-eight patients had GWNS stroke scale score of 3 or 4, with 57 having confirmed LVO and 1 presenting after a seizure. The GWNS stroke score ≥3 (0.86) correlated with LVO better than NIHSS (0.67), regardless of hemisphere side involvement. The GWNS stroke scale score of ≥3 also was effective in detection of proximal and distal blood vessels occlusion in the anterior circulation (Internal carotid artery, middle cerebral artery and its branches). A GWNS stroke scale score of ≥3 with presence of gaze was the most predictive for LVO (0.9) followed by neglect/disregards (0.8). The time to obtain GWNS stroke scale was 1.5 minutes (range 1-3) and time to obtain/interpretation CTA was 41.3 +/- 7.4 minutes after emergency department arrival (range: 29-51 minutes). Conclusions: Our Gaze Weakness Neglect Speech stroke scale can be performed rapidly in the emergency department and is highly predictive of LVO in the internal carotid artery, middle cerebral artery and middle cerebral branches. A GWNS stroke scale score of ≥3 is highly predictive of LVO, especially when gaze or neglect is present.

The use of peer-led health education in increasing medication adherence and antiretroviral therapy retention has been advocated. Therefore, this study investigated the effect of peer education on medication adherence and antiretroviral-therapy retention practices among Youth Living with HIV in Niger state, Nigeria. The study was a quasi-experimental design in two selected hospitals. One hospital was assigned to a one-hour peer-led health education session for six weeks, and the 2nd served as the control group. Data were collected at baseline, immediate post-intervention, and at the sixth-week follow-up. Data were analyzed using descriptive and inferential statistics at a 0.05 level of significance. Majority of respondents practice Islam and are within the ages of 20-24 years (control: 100%, 89%; intervention: 83%, 73%), from the Hausa Ethnic group (control: 62%; intervention: 56%). Majority of respondents in the control group have Islamic education (50%) and Secondary education (50%), while the majority of those in the intervention group have primary education (35%), secondary (29%), tertiary (19%) and Islamic (17%) respectively. Medication adherence and ART retention was higher in the intervention group (27%, 16%) compared with the control (17%, 9%). A significant association between knowledge and perception due to peer education on medication adherence was found (24%, 80%) in the intervention group and (11%, 36%) in the control group. Subsequently, the 6th week follow-up sustained findings from the intervention period on medication adherence and ART retention (27%, 16%) in the intervention group compared with control group (17%, 9%). Similarly, knowledge and perception follow-up post intervention was sustained (24%, 80%) in the intervention group and (11%, 36%) in the control group. Interventions leveraging peer-led health education enhanced HIV medication adherence and antiretroviral therapy retention practices among youths. Thus, we recommend scale-up of the structured peer-led curriculum and integration into the health systems to improve health outcomes among HIV positive youths, achieve epidemic control and accelerate progress for the UNAIDS 95:95:95 goals.","PeriodicalId":94137,"journal":{"name":"Medical research archives","volume":"142 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86235547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The protein serves two critical functions simultaneously: it delivers nutrients to growing embryo cells and immature myeloid-derived suppressor cells, so the mother’s immune system doesn’t attack the embryo. The protein is present in minuscule amounts in adults and elevated alpha-fetoprotein levels serve as pregnancy or tumor markers. Exogenous alpha-fetoprotein has a new application as an immunotherapy drug. It can deliver drugs in a natural shuttle manner to myeloid-derived suppressor cells and stimulate them to calm the hyperactive immune response during many physiological and pathological conditions. On the other hand, alpha-fetoprotein loaded with toxins kills myeloid-derived suppressor cells and unleashes natural killer cells and cytotoxic lymphocytes to erase cancer. Most cancers have cells that specifically bind alpha-fetoprotein, and this protein targets chemotherapy to them also. So, alpha-fetoprotein with toxins combines both potent cancer immunotherapy and targeted chemotherapy activities. Alpha-fetoprotein can be chemically conjugated with or bind toxins non-covalently. Both preparations have demonstrated superior efficacy and safety compared to chemotherapy alone. Alpha-fetoprotein-toxin immuno/chemotherapy is not personalized. There is no need to preselect patients for cancer treatments as they have elevated myeloid-derived suppressor cell levels. The anti-cancer efficacy of porcine alpha-fetoprotein non-covalent complexes with selected toxins administered orally is a remarkable discovery that needs research. Cancer treatment and prevention are different issues, and they could need different approaches. Alpha-fetoprotein administration with drugs or toxins could be as effective in early cancer and metastasis prevention as mifepristone pills in pregnancy prevention.","PeriodicalId":94137,"journal":{"name":"Medical research archives","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82924711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can be used directly over wounds or used to grow stem cells by different culture methods. The hAM can be used “fresh” i.e., +4O glycerol preserved or “cryopreserved”. Methods: In this literature review, we searched ‘PubMed’, ’Web of Science’ and ’SCOPUS’ for experimental models, RCT, Observational studies, case series, and case reports involving the usage of hAM in the treatment of neonatal and paediatric (<14 yrs.) patients, published in from 1993 to April 2022. The search included the keywords, “amnion”, “biomaterials”, “biological dressing”, “clinical study”, “congenital defects”, “human amniotic membrane”, “paediatric wound”, “neonatal wounds”, and “regenerative medicine”. The Search was extended by snowballing the reference list of all included studies. Results: The final analysis included one experimental RCT, three review articles, and twelve case reports. The experimental studies were in rat, pup, and porcine models. The paediatric second-and third-degree thermal burn followed by paediatric ocular diseases viz corneal epithelial ulcers, conjunctiva reconstruction following Steven Johnson Syndrome, and scarring after surgery of strabismus were the most common indications for the usage of AM. Five cases of meningomyelocele repair (intradural & extradural placement of AM) and 2 cases of gastroschisis repair (as an antiadhesive layer) were reported. Freeze-dried hAM is most frequently used in clinical practice. Autologous hAM was used in antenatally detected birth defects. In the adults, the fresh hAM was found equally effective as freeze-dried AM, but with the risk of transmission of contagious diseases. The literature on Fresh amnion is deficient in paediatric patients. Conclusion: hAM as a skin substitute in paediatric wounds/defects has shown an enhanced rate of healing. However, further studies, regarding the utility of hAM in the management of paediatric wounds, congenital anatomical defects, and diseases along with analysis of outcome and economic constraints in developing countries are needed.","PeriodicalId":94137,"journal":{"name":"Medical research archives","volume":"55 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90054991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: COVID-19 comprises a coronavirus severe inflammatory disease infecting tissue populated by ACE-2 receptors of the upper and lower respiratory tract and AEC causing an overexpression of pro-inflammatory cytokines. Once in the lungs, viremic spread and cytokine profusion progresses into multi-organ hyperinflammation of visceral epithelium, vascular endothelium, and neurons of the CNS, PNS, ANS, and brain with long-term sequelae. In response to an oxidative state, red and NIR PBM down-regulates proinflammatory cytokines, activating M2 macrophages and Th2 helper cells to increase anti-inflammatory immune response in accordance with a biphasic dose response. Published reports confirm efficacious therapy of COVID-19 using conformal LED pads or scanned lasers. Results: A series of two acute COVID case studies comprising 69 ambulatory (stage 1-to-5) and five stage-6 hospitalized patients confirm the efficacious impact of whole-organ deep-tissue PBM using algorithmically-pulsed conformal LED pad optical delivery methods. Together, acute symptomatic recovery from two 64-84 min PBM sessions occurred within three days for 62/62 patients. Full recovery occurred within four sessions for all PBM patients (all but two cases resolved within one week). Prophylactic benefits were recorded in 17/17 asymptomatic-to-mild (stage 0-1) patients exposed to viral shedding of infected family members. PBM of long COVID outcomes include total resolution of dyspnea, ability to maintain SpO2 above 97% without oxygen supplementation, relief from digestive distress, elimination of brain fog, improved memory recall, restored executive function, and symptomatically managing emotional deficits. Total whole-organ PBM treatments to date comprise approximately three-hundred fifty cases comprising 60% acute COVID-19, 20% metabolic and respiratory long COVID, and 20% neurological long COVID. Unresolved cases totaling 0.25% include two cases of severe long COVID anxiety and nosophobia where PBM was found to deliver only short-term palliative relief. Conclusion: Ongoing results increasingly support the application of whole-organ deep tissue PBM in the treatment of acute and long COVID-19. Both conformal LED pads and scanning lasers demonstrate favorable outcomes. LED pads deliver higher fluences than scanned lasers in the same session times. Further studies of the prophylactic benefits of PBM are indicated.","PeriodicalId":94137,"journal":{"name":"Medical research archives","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80819208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
