Shalaby RM, El-Kosery SM, Soliman MM, Osman DA. Effect of blue light emitting diode therapy on recurrent vulvovaginal candidiasis: A randomized assessor-blinded controlled trial. PHYSIOTHERAPY RESEARCH INTERNATIONAL 2024; 29:e2129. [PMID: 39223951 DOI: 10.1002/pri.2129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2024] [Revised: 08/07/2024] [Accepted: 08/21/2024] [Indexed: 09/04/2024]
Abstract
OBJECTIVE Vulvovaginal Candidiasis (VVC) is a prevalent genital infection in women of reproductive age and requires effective non-drug therapies. Therefore, this study aimed to investigate the effect of blue light emitting diode (LED) therapy as an alternative treatment for recurrent VVC due to its proven antimicrobial properties. The safety and non-invasiveness of LED therapy make it a promising option for sensitive tissue applications. MATERIALS AND METHODS This randomized controlled trial recruited 60 women with culture-confirmed VVC. Participants were randomly allocated to two groups. Group A (control group) received standard antifungal treatment with Gynoconazol 0.8% vaginal cream for three consecutive nights (n = 30). Group B (study group) received the same antifungal treatment plus two 60-min sessions of blue LED therapy directed at the vagina and vulva, with the sessions separated by two days (n = 30). Candida count (via CHROMagar™ Candida) and vaginal pH (via AD110-AD111 m) were assessed at baseline and one week after initiating treatment. RESULTS Post-treatment, group (B) demonstrated a significantly greater reduction in Candida count compared to group (A) (mean difference (MD) 8.267; 95% Confidence Interval (CI) 6.723-9.811; p = 0.0001). However, there was no statistically significant difference in vaginal pH between the groups (MD -0.03; 95% CI -0.244-0.178; p = 0.749). CONCLUSION Blue LED therapy effectively reduces Candida count in women with recurrent VVC without adversely affecting the vaginal pH, highlighting its safety and efficacy as a treatment modality.

Abstract
Sulfur electrophiles constitute an important class of covalent small molecules that have found widespread applications in synthetic chemistry and chemical biology. Various electrophilic scaffolds, including sulfonyl fluorides and arylfluorosulfates as recent examples, have been applied for protein bioconjugation to probe ligand sites amenable for chemical proteomics and drug discovery. In this review, we describe the development of sulfonyl-triazoles as a new class of electrophiles for sulfur-triazole exchange (SuTEx) chemistry. SuTEx achieves covalent reaction with protein sites through irreversible modification of a residue with an adduct group (AG) upon departure of a leaving group (LG). A principal differentiator of SuTEx from other chemotypes is the selection of a triazole heterocycle as the LG, which introduces additional capabilities for tuning the sulfur electrophile. We describe the opportunities afforded by modifications to the LG and AG alone or in tandem to facilitate nucleophilic substitution reactions at the SO2 center in cell lysates and live cells. As a result of these features, SuTEx serves as an efficient platform for developing chemical probes with tunable bioactivity to study novel nucleophilic sites on established and poorly annotated protein targets. Here, we highlight a suite of biological applications for the SuTEx electrophile and discuss future goals for this enabling covalent chemistry.

Abstract
The structure, relative stability and bonding of complexes formed by the interaction between Ga(+) and a large set of compounds, including hydrocarbons, aromatic systems, and oxygen-, nitrogen-, fluorine and sulfur-containing Lewis bases have been investigated through the use of the high-level composite ab initio Gaussian-4 theory. This allowed us to establish rather accurate Ga(+) cation affinity (GaCA) and Ga(+) cation basicity (GaCB) scales. The bonding analysis of the complexes under scrutiny shows that, even though one of the main ingredients of the Ga(+) -base interaction is electrostatic, it exhibits a non-negligible covalent character triggered by the presence of the low-lying empty 4p orbital of Ga(+) , which favors a charge donation from occupied orbitals of the base to the metal ion. This partial covalent character, also observed in AlCA scales, is behind the dissimilarities observed when GaCA are compared with Li(+) cation affinities, where these covalent contributions are practically nonexistent. Quite unexpectedly, there are some dissimilarities between several Ga(+) -complexes and the corresponding Al(+) -analogues, mainly affecting the relative stability of π-complexes involving aromatic compounds.

Abstract
The synthesis of N-arylated pyrroles and indoles is documented, as well as their functionalization by deprotonative metallation using the base in situ prepared from LiTMP and ZnCl2·TMEDA (1/3 equiv). With N-phenylpyrrole and -indole, the reactions were carried out in hexane containing TMEDA which regioselectively afforded the 2-iodo derivatives after subsequent iodolysis. With pyrroles and indoles bearing N-substituents such as 2-thienyl, 3-pyridyl, 4-methoxyphenyl and 4-bromophenyl, the reactions all took place on the substituent, at the position either adjacent to the heteroatom (S, N) or ortho to the heteroatom-containing substituent (OMe, Br). The CH acidities of the substrates were determined in THF solution using the DFT B3LYP method in order to rationalize the experimental results.

Abstract
Various decouplings of the electron propagator have been employed to provide theoretical comparison to experimental electron detachment energies for the pyrrolide, imidazolide, and pyrazolide anions. Predictions for isoelectronic anions in which CH groups are replaced by N atoms also are reported. The ab initio electron propagator results agree closely with experimental values, and the associated Dyson orbitals provide a detailed catalog of bonding changes as the number and positions of N atoms vary within the set of pentagonal aromatic anions.
