Introduction: The modified Ferriman-Gallwey (mFG) scale is accepted as a useful clinical scoring system in the evaluation of hirsutism.
Aim: To prevent overlooking hirsutism diagnoses and facilitate patient examinations in ongoing pandemic conditions by simplifying the mFG score.
Material And Methods: This study included 227 patients who were diagnosed with hirsutism and had mFG scores of ≥ 8.
Aims: Tamanu is a plant oil derived from the fruit and seeds of the tree. Although scientific data on tamanu oil are limited, it is recommended worldwide for the treatment of abrasions, burns, diabetic wounds and scars. This study aimed to compare the wound healing efficacy of the topical use of tamanu oil with a reference drug in rats.

During the partial curfews implemented in the pandemic period, the pediatric patients presenting to the dermatology clinic of our hospital were examined taking the necessary precautions. We aimed to identify children and adolescent cases requiring dermatology services and their urgency when the number of COVID-19 cases was rapidly increasing and partial curfews were being imposed in Turkey.

Earlier reports have established that chitin isolates from each body part of an insect cuticle can exhibit diverse physicochemical properties. But it is still unknown if the gender of the insect can influence characteristics of chitin isolates from different body parts. The present study addresses this question.

This is the first study to explain the differences in the physicochemical properties of chitin and chitosan obtained from the nymphs and adults of Dociostaurus maroccanus using the same method. Fourier transform infrared spectroscopy, thermogravimetric analysis and x-ray diffraction analysis results demonstrated that the chitins from both the adults and nymphs were in the α-form. The chitin contents of the adults (14%) and nymphs (12%) were of the same order of magnitude.

The quality of chitin in such highly specialised body parts deserves more detailed examination. Chitin in the corneal (ommatidial) lenses of dragonfly (Sympetrum fonscolombii) compound eyes was isolated by using the classical chemical method.

It was observed that the antimicrobial activity of the low molecular weight scorpion chitosan (LMWSC) was specific to bacterial species in general rather than gram-negative or gram-positive bacterial groups.

The presence of chitin in the fungal cell wall has been revealed by previous studies. Considering the presence of fungi in the lichens, this work determines the presence of chitin in a cosmopolitan lichen species Xanthoria parietina.

Chitins and chitosans obtained from larva and adult Colorado potato beetles (Leptinotarsa decemlineata) were physico-chemically characterized and differences between adults and larvae were identified. The dry weight chitin contents of the adult Colorado potato beetles and larvae were determined as 20% and 7%, respectively. The chitin produced chitosan yields of 72% from the adult Colorado potato beetles and 67% from the larvae.

Differences in the physichochemical properties of the chitin structure of the exoskeleton of seven species from four genera were investigated in this study. The same method was used to isolate the chitin structure of the seven species. The physicochemical properties of the isolated chitins were revealed by ESEM, FTIR, TGA and XRD analyses.

New application areas for chitin and its derivatives have been extensively investigated and there is a solid, growing demand for new chitin sources. In this present study, chitin content of Daphnia magna resting egg (18-21%) was determined for the first time. FTIR, elemental analysis, TGA, XRD and SEM studies revealed the structural and thermal properties of extracted α-chitin.
