This trial compared the efficacy and safety of biosimilar cetuximab versus innovator cetuximab (IC) in combination with platinum-based chemotherapy in patients with recurrent locoregional or metastatic SCCHN.

Methods: This phase III trial is a multicenter, randomized, double-blind and parallel group study performed in Indian patients with recurrent locoregional or metastatic SCCHN.

The Role of 20% Ethanol in Enhancing Pterygium Surgery Outcomes: A Clinical Study.

Introduction Pterygium is an ocular surface disorder characterized by a hyperplastic growth of conjunctiva encroaching over the cornea. It causes redness, watering, and foreign body sensation. Surgical excision is the preferred mode of treatment when there is encroachment over the visual axis, chronic irritation, restricted ocular motility, and cosmetic concerns.

Targetoid Hair Regrowth Pattern in Alopecia Areata: A Case Series.

Alopecia areata (AA) is an autoimmune disorder leading to nonscarring hair loss of the scalp and/or body. Atypical hair regrowth in AA is considered a rare phenomenon. Many paradoxical forms of hair regrowth have been described in AA.

The Current Understanding of Mechanistic Pathways in Zeolite Crystallization.

Zeolite catalysts and adsorbents have been an integral part of many commercial processes and are projected to play a significant role in emerging technologies to address the changing energy and environmental landscapes. The ability to rationally design zeolites with tailored properties relies on a fundamental understanding of crystallization pathways to strategically manipulate processes of nucleation and growth. The complexity of zeolite growth media engenders a diversity of crystallization mechanisms that can manifest at different synthesis stages.

"Chatting with ChatGPT": Analyzing the factors influencing users' intention to Use the Open AI's ChatGPT using the UTAUT model.

Open AI's ChatGPT has emerged as a popular AI language model that can engage in natural language conversations with users. Based on a qualitative research approach using semistructured interviews with 32 ChatGPT users from India, this study examined the factors influencing users' acceptance and use of ChatGPT using the unified theory of acceptance and usage of technology (UTAUT) model. The study results demonstrated that the four factors of UTAUT, along with two extended constructs, i.

Designed and validated novel allele-specific primer to differentiate Kernel Row Number (KRN) in tropical field corn.

Background: Kernel row number (KRN) is an important yield component trait with a direct impact on the productivity of maize. The variability in KRN is influenced by the inflorescence meristem size, which is determined by the CLAVATA-WUSCHEL pathway. A CLAVATA receptor-like protein, encoded by the FASCIATED EAR2 (fea2gene), enhances the growth of inflorescence meristem and is thus involved in the determination of KRN.

Electrochemical, Ultrasensitive, and Selective Detection of Nitrite and HO: Novel Macrostructured Phthalocyanine with Composite MWCNTs on a Modified GCE.

In the current study, the synthesis of tetra-4-(2-methoxyphenoxy) carboxamide cobalt(II) amide-bridged phthalocyanine (CoTMePhCAPc) is described, as well as its characterization by Fourier transform infrared (FT-IR), UV-visible, and mass spectroscopy; powder X-ray diffraction (PXRD); thermogravimetric analysis (TGA); scanning electron microscopy (SEM); and electrochemistry. Sensing of nitrite (NO) and hydrogen peroxide (HO) simultaneously was done on CoTMePhCAPc with the composite multiwalled carbon nanotube (MWCNT)-modified glassy carbon electrode (CoTMePhCAPc/MWCNT/GCE) in the range of linear absorption (NO and HO: CV 50-750, differential pulse voltammetry (DPV) 50-750, CA 50-500 nmol L), lower detection limit (NO and HO: CV 10.5 and 12.

Erosive Pustular Dermatosis of the Scalp: Report of Three Cases.

Erosive pustular dermatosis of the scalp is a chronic cutaneous condition presenting with areas of erosions and pustules, healing with scarring and alopecia. We report three such cases presenting with pus-filled lesions of the scalp with nonspecific pathological changes. This condition is often misdiagnosed and shows a poor response to antibiotics.

The Use of Botulinum Toxin-A as an Adjunctive Treatment for Facial Atrophic and Hypertrophic Scars After Surgical Correction.

Background: Facial wounds, especially the ones lying perpendicular to the Lines of Langer, heal poorly. Several methods have been attempted to rectify this, but most of them do not target the underlying pathological process of scarring. Botulinum Toxin-A (BTA) has been successfully used for atrophic and hypertrophic scars.

Prevalence of frailty and its association with lifestyle factors among elderly in rural Bengaluru.

Background: There are nearly 10.4 crores elderly in India, with 65% of them living in rural areas. Accessibility to healthcare is limited in rural areas.

Dosimetric comparison and validation of Eclipse Anisotropic Analytical Algorithm (AAA) and AcurosXB (AXB) algorithms in RapidArc-based radiosurgery plans of patients with solitary brain metastasis.

Stereotactic radiosurgery (SRS) is increasingly being used to manage solitary or multiple brain metastasis. This study aims to compare and validate Anisotropic Analytical Algorithm (AAA) and AcurosXB (AXB) algorithms of Eclipse Treatment Planning System (TPS) in RapidArc-based SRS plans of patients with solitary brain metastasis. Twenty patients with solitary brain metastasis who have been already treated with RapidArc SRS plans calculated using AAA plans were selected for this study.

Varying the Directionality of Protein Catalysts for Aldol and Retro-Aldol Reactions.

Natural aldolase enzymes and created retro-aldolase protein catalysts often catalyze both aldol and retro-aldol reactions depending on the concentrations of the reactants and the products. Here, we report that the directionality of protein catalysts can be altered by replacing one amino acid. The protein catalyst derived from a scaffold of a previously reported retro-aldolase catalyst, catalyzed aldol reactions more efficiently than the previously reported retro-aldolase catalyst.

Efficacy of 532-nm Q-switched Nd:YAG Laser in the Treatment of Lip Melanosis.

Introduction: Lip pigmentation is frequently encountered in the Dermatology outpatient department. No effective treatment is available so far. Topical treatment requires longer time and is often unsatisfactory.

Intramolecular Mannich and Michael Annulation Reactions of Lactam Derivatives Bearing Enals To Afford Bicyclic N-Heterocycles.

Acid-catalyzed intramolecular vinylogous Mannich reactions and intramolecular Michael reactions affording pyrrolizinone-fused N-heterocycles from hydroxylactam derivatives bearing enals have been developed. Depending on the substituent on the hydroxylactam, the enal moiety acted either as a nucleophile (i.e.
