Here, we present an experimental method that redistributes the optical energy among the lobes of high-order standard Hermite-Gaussian (SHG) laser modes in a controlled manner. We numerically designed diffractive optical elements, displayed over a spatial light modulator for redistribution of optical energy that converts low and moderate intense lobes into all highly intense lobes and vice versa at the Fourier plane. Such precise generation of modulated HG (MHG) laser modes offers a maximum number of highly intense lobes compared to SHG modes. Hence, we envisage that MHG beams may surpass SHG beams in many applications, such as particle manipulation and optical lithography, where highly intense lobes play a significant role.

Background: Anoxic brain injury is a potentially lethal condition characterized by cerebral hypoperfusion and irreversible neuronal injury. Arterial spin-labeling (ASL) perfusion and diffusion-weighted imaging (DWI) magnetic resonance imaging (MRI) have been proposed as tools to detect cerebral ischemic changes and may aid in the assessment of anoxic injury.
Aim: To explore the relationship between regional ASL perfusion patterns and clinical outcomes following cardiac arrest.

Perivascular epithelioid cell tumors (PEComas) are rare, typically benign soft tissue tumors that can develop at various anatomic sites. Malignant PEComas are rarer entities but may present aggressively with metastasis to the lungs or local recurrence years after initial presentation. In unresectable or metastatic cases, treatment options are limited due to the resistance of PEComas to chemotherapy and radiotherapy.

This study details the synthesis of a novel ligand, ()-5-chloro-'-(2-hydroxy-3-methoxybenzylidene) thiophene-2-carbohydrazide ligand (for short, H2L), and its tetranuclear Cu(II) complex (Cu4L4), together with their X-ray crystal structures and the magnetic properties and EPR spectra of Cu4L4 within the 4-300 K temperature range. Furthermore, we report the spectroscopic characterization (FTIR and UV-Vis) of the compounds and perform a Hirshfeld analysis of their non-covalent interactions, along with certain quantum chemical calculations. H2L crystallizes in the monoclinic space group with = 8 molecules per unit cell and the Cu4L4 complex crystallizes in the tetragonal space group 4/ with = 4.

Background: Anti-Ma2 antibody encephalitis is a rare paraneoplastic autoimmune encephalitis (AE) caused by anti-Ma2 antibody. Creutzfeldt-Jakob disease (CJD), a group of human prion diseases, is a rapidly advancing and fatal neurodegenerative disorder. The two diseases may display comparable clinical symptoms that are easily misdiagnosed.

This study investigated the liver composition in diabetic-induced mice after photobiomodulation (PBM) treatment using nuclear magnetic resonance (NMR) to identify potential molecular alterations. Tissue biopsies were removed from the left lobes of rat livers. Each biopsy was frozen in liquid nitrogen and stored at -80 °C for NMR analysis.
