Safety of free fibula flap harvest in IIIA and IIIB tibio-peroneal trunk variations.

Introduction: In head and neck cancer malignancies, free fibula flap is the gold standard for reconstruction of segmental bone defects owing to its predictable anatomy, long bone length, and feasibility for multiple osteotomies. However, sometimes because of variations in anatomy of tibio-peroneal trunk, it is a dilemma for the surgeons to use free fibula flap for reconstruction. This case series aimed to evaluate the safety of harvest of fibula in such cases in terms of acute and chronic donor-site complications.

First report of Fusarium incarnatum-equiseti species complex as the causal agent of pod rot of black gram (Vigna mungo L.) in India.

Black gram (Vigna mungo L.) is important pulse crop and is the third-most cultivated pulse in India (Swaminathan et al. 2023).

Visible-Light-Induced Photocatalytic Trifluoromethylation of Bunte Salts: Easy Access to Trifluoromethylthiolated Synthons.

A metal-free visible-light-induced trifluoromethylation of Bunte salts of α-bromoketones/alkyl bromide/benzyl bromides/functionalized allyl (Baylis-Hillman) bromides has been accomplished using Langlois' reagent in the presence of inexpensive eosin Y as a photocatalyst to form the privileged trifluoromethylthiolated synthons. The method is straightforward, operationally simple, and endowed with broad substrate scope and good functional group tolerance.

Iodine-catalyzed thioallylation of indoles using Bunte salts prepared from Baylis-Hillman bromides.

Metal-free iodine-catalyzed regioselective thioallylation of indoles has been accomplished at room temperature using Bunte salts prepared from Baylis-Hillman bromides. The resulting multi-functional C3 thioallylated indoles exhibit ample structural diversity and good functional group tolerance.

Probing the Griffiths like phase, unconventional dual glassy states, giant exchange bias effects and its correlation with its electronic structure in Pr Sr CoMnO.

Crystal, electronic structure, dc and ac magnetization properties of the hole substituted (Sr) and partially B-site disordered double perovskite Pr Sr CoMnO system have been investigated. The XRD pattern analysis showed a systematic decrease in the lattice parameters owing to the enhanced oxidation states of the Co/Mn ions. The electronic structure study by XPS measurements suggested the presence of mixed valence states of the B-site ions (Co /Co and Mn /Mn) with significant enhancement of the average oxidation states due to hole doping.

Investigation of multi-mode spin-phonon coupling and local B-site disorder in PrCoFeO by Raman spectroscopy and correlation with its electronic structure by XPS and XAS studies.

Electronic structure of PrCoFeO (at 300 K) was investigated by x-ray photoemission spectroscopy (XPS) and x-ray absorption spectroscopy techniques. All three cations, i.e.
