Preventable morbidities are serious conditions that have the potential to cause serious harm or death of the patient. One of the preventable morbidities is Gossypiboma or involuntary leaving of surgical sponge inside the body. The implication for the patient and the surgeon is grave.

Objective The purpose of this study is to isolate the organisms which are developing resistance and to recognize the drugs against which resistance has emerged so that antibiotic policy can be formulated for the proper and effective use of antibiotics. Setting and design An observational study was conducted for a period of six months from July 1, 2021 and December 31, 2021 in LGH. Methods Statistics regarding the culture and sensitivity of the organisms isolated from different sources were collected from the surgery department.

Recapitulation of the microstructural organization of cellular and extracellular components found in natural tissues is an important but challenging feat for tissue engineering, which demands innovation across both process and material fronts. In this work, a highly versatile ultrasound-assisted biofabrication (UAB) approach is demonstrated that utilizes radiation forces generated by superimposing ultrasonic bulk acoustic waves to rapidly organize arrays of cells and other biomaterial additives within single and multilayered hydrogel constructs. UAB is used in conjunction with a novel hybrid bioink system, comprising of cartilage-forming cells (human adipose-derived stem cells or chondrocytes) and additives to promote cell adhesion (collagen microaggregates or polycaprolactone microfibers) encapsulated within gelatin methacryloyl (GelMA) hydrogels, to fabricate cartilaginous tissue constructs featuring bulk anisotropy.

Article Synopsis
  • Gelatin methacryloyl (GelMA) hydrogels are versatile biomaterials useful for drug delivery, tissue engineering, and disease modeling, featuring both thermal and UV cross-linking properties that affect their structural characteristics.
  • The study investigates how these cross-linking methods and variations in GelMA solution temperature and UV exposure time influence hydrogel properties like stiffness, pore size, degradation rate, and how these changes affect the behavior of encapsulated cells.
  • Findings suggest that lower temperatures and prolonged UV exposure create stiffer hydrogels with smaller pores, preferred for maintaining cell shape and promoting cell proliferation, whereas higher stiffness levels lead to poor cell attachment and increased inflammation markers in stem cells.

We present the discovery of a charge density wave (CDW) ground state in heavily electron-doped molybdenum disulfide (MoS). This is the first observation of a CDW in any (column 6) transition metal dichalcogenide (TMD). The band structure of MoS is distinct from the and TMDs in which CDWs have been previously observed, facilitating new insight into CDW formation.

We investigate the chemical and structural configuration of acetophenone on Si(0 0 1) using synchrotron radiation core-level spectroscopy techniques and density functional theory calculations. Samples were prepared by vapour phase dosing of clean Si(0 0 1) surfaces with acetophenone in ultrahigh vacuum. Near edge x-ray absorption fine structure spectroscopy and photoelectron spectroscopy measurements were made at room temperature as a function of coverage density and post-deposition anneal temperature.
