Background:
Parkinson’s disease is a debilitating and the second most common neurodegenerative disorder with a high prevalence. Parkinson’s disease has a multifaceted etiology characterized by an altered redox state and an excessive inflammatory response. In this study, we investigated the potential neuroprotective properties of carvacrol in a haloperidol-induced Parkinson’s model. In female Sprague-Dawley rats, the animal Parkinson model was induced by intraperitoneally administering 1 mg / kg of haloperidol once daily for fifteen days. Carvacrol was administered at a dose of 25 and 50 mg / kg once daily for fifteen days before haloperidol administration. In order to further illustrate the vital role of the tumor necrosis factor (TNF-α) pathway, we administered 50 mg / kg of the TNF-α inhibitor thalidomide once daily for 15 days.
Results:
Our results showed that haloperidol-induced motor deficits, changed endogenous antioxidant enzymes, along with higher levels of inflammasome (NLRP3) and other inflammatory mediators. Moreover, increased levels of lipid peroxidase (LPO) indicated a significant rise in oxidative stress due to haloperidol. Moreover, carvacrol reduced these effects by preventing pyroptosis mediated by the inflammasome (NLRP3) and TNF-α. The administration of thalidomide mitigated oxidative stress and suppresses inflammatory pathways through the augmentation of the intrinsic antioxidant system. Further, co-treatment of carvacrol with thalidomide synergized the neuroprotective effect of carvacrol as demonstrated by various immunoassays and histology analyses.
Conclusions
Taken together, our findings suggest that carvacrol mitigated haloperidol-induced Parkinson-like symptoms, partially through the downregulation of TNF-α and NLRP3.

Environmental Determinants in Sustaining the Transmission of Lymphatic Filariasis: A Systematic Review
IntroductionSince mass drug administration continues in many of the endemic countries, it is vital to synthesise evidence to adapt the challenges contributed by the environments. As such, the aim of this review was to explore relationship between lymphatic filariasis prevalence and potential environmental determinants .MethodsWe searched the electronic databases PubMed, Web of Science, Cochrane, and Scopus between Jan 1, 2013, and Dec 31, 2022, for studies fulfilling the following criteria: it was an original article investigating the environmental determinants associated with transmission of lymphatic filariasis; and the study was published in English. The quality assessment tools for observational studies from the National Heart, Lung, and Blood Institute was used to assess the study quality. This systematic review was registered with the PROSPERO database (CRD42023393018).ResultsWe identified 409 potentially eligible published articles, of which 11 met our inclusion criteria. The main environmental determinants associated with lymphatic filariasis transmission were Normalised Difference Vegetation Index (NDVI), land cover, distance to waterbody, rainfall/precipitation, elevation, slope, day land surface temperature, average annual temperature, house type and distance to stable light. ConclusionsThis review is one of the steps towards understanding the associations between environmental determinantsand transmission of lymphatic filariasis. These results can be used in future evidence-based strategies to strengthen surveillance and control strategies.

Journal of the Korean Association of Oral and Maxillofacial Surgeons 2024;50(1):27-34
Objectives:
Surgical intervention for removal of an impacted third molar can lead to significant pain and swelling. Corticosteroids show promise for mitigating postoperative sequelae across various surgical contexts. The use of corticosteroids following minor oral surgery, though controversial, has already been proven effective. However, little research has explored peroral prescription of corticosteroids despite its convenience for outpatients and for non-surgeons like implantologists and periodontists and others who don’t have access to needle injections. The aim of this study was to address a void in the literature by comparing the effects of two styles of preoral administration of prednisolone after surgical removal of the mandibular third molar and to determine which style minimizes postoperative sequelae.
Materials and Methods:
A randomized, split-mouth clinical study was conducted to investigate the efficacy of two different styles of preoral prednisolone in mitigating postoperative sequelae following surgical extraction of impacted mandibular third molars. Fifteen participants were enrolled in the study. Random selection was used to determine the prescription style for the right and left mandibular arch. Group A included those who received a single dose of prednisolone 25 mg, while group B received prednisolone 5 mg postoperatively for a period of three days (5 mg three times/day on the first postoperative day, 5 mg twice/day on the second postoperative day; 5 mg once/day on the third postoperative day).
Results:
There was a significant difference in the distance between the corner of the mouth and tragus, which decreased with the time interval with respect to group B when compared to group A.
Conclusion
The present study showed that a three-day tapered dose of prednisolone postoperatively was more effective in reducing post-extraction sequelae than a single-dose regimen.

Background:
Reduced harvest volumes in pediatric donors appear to have the potential to reduce donor-associated risks while maintaining engraftment in recipients; however, the allowable harvest volume reduction remains undefined.
Methods:
We retrospectively analyzed the data pairs of 553 bone marrow (BM) harvests from pediatric (age at harvest <18 yr) sibling donors and clinical outcomes of 553 pediatric (age at infusion <14 yr) transplant-naïve recipients to assess the optimal BM harvest volume needed from pediatric donors to obtain the desired CD34+ cell count (≥3.0×10 6 cells per kg of recipient weight), and to study its impact on the clinical outcomes of transplantation in pediatric recipients.
Results:
The minimum desired CD34+ cell count of ≥3.0×10 6 per kg of recipient weight was achieved for 506 (95.3%) of donor-recipient pairs. The median CD34+ cell yield was 6.4×10 6 per kg of recipient weight (range, 1.2‒33.8×10 6 ) in donors younger than 5 years old at harvest, 4.7×10 6 (range, 0.3‒28.5×10 6 ) in donors aged 5‒10 years and 2.1×10 6 range, 0.3‒11.3×10 6 ) in donors older than 10 years (P <0.001).
Conclusion
The infused CD34+ cell dose (×10 6 cells/kg of recipient weight) had no impact on GRFS; however, a CD34+ cell dose of >7×10 6 cells/kg of recipient weight did not improve hematopoietic recovery
10.Translabial ultrasound for pelvic organ prolapse

Obstetrics & Gynecology Science 2023;66(2):69-75
Pelvic organ prolapse (POP) is a significant public health concern in women and a common cause of gynecological surgery in elderly women. The prevalence of POP has increased with an increase in the aging population. POP is usually diagnosed based on pelvic examination. However, an imaging study may be necessary for more accurate diagnosis. Translabial ultrasound (TLUS) was used to assess diverse types of POP, particularly posterior-compartment POP. It is beneficial to distinguish between true and false rectocele, and detect the rectocele as clinically apparent. TLUS can also establish whether the underlying cause is a problem of the rectovaginal septum, perineal hypermobility, or isolated enterocele. TLUS also plays a role in differentiating POP from conditions that mimic POP. It is a simple, inexpensive, and non-harmful diagnostic modality that is appropriate for most gynecologic clinics.
