Eco-friendly alkali lignin-assisted water-based graphene oxide ink and its application as a resistive temperature sensor.

Inkjet-printable ink formulated with graphene oxide (GO) offers several advantages, including aqueous dispersion, low cost, and environmentally friendly production. However, water-based GO ink encounters challenges such as high surface tension, low wetting properties, and reduced ink stability over prolonged storage time. Alkali lignin, a natural surfactant, is promising in improving GO ink's stability, wettability, and printing characteristics.

A comprehensive review on facemask manufacturing, testing, and its environmental impacts.

The coronavirus pandemic (COVID-19) is currently the biggest threat to human lives due to its rapid transmission rate causing severe damage to human health and economy. The transmission of viral diseases can be minimized at its early stages with proper planning and preventive practices. The use of facemask has proved to be most effective measure to curb the spread of virus along with social distancing and good hygiene practices.

Laparoscopic vs. Open Gastrectomy for Locally Advanced Gastric Cancer: A Propensity Score-Matched Retrospective Case-Control Study.

Introduction: Minimally invasive surgery has been increasingly used in the treatment of gastric cancer. While laparoscopic gastrectomy has become standard therapy for early-stage gastric cancer, especially in Asian countries, the use of minimally invasive techniques has not attained the same widespread acceptance for the treatment of more advanced tumours, principally due to existing concerns about its feasibility and oncological adequacy. We aimed to examine the safety and oncological effectiveness of laparoscopic technique with radical intent for the treatment of patients with locally advanced gastric cancer by comparing short-term surgical and oncologic outcomes of laparoscopic versus open gastrectomy with D2 lymphadenectomy at two Western regional institutions.

The technology of tongue and hard palate contact detection: a review.

The tongue and hard palate play an essential role in the production of sound during continuous speech. Appropriate tongue and hard palate contacts will ensure proper sound production. Electropalatography, also known as EPG, is a device that can be used to identify the location of the tongue and hard palate contact.

Collagenous spherulosis of the breast. Case report.

We report a case of collagenous spherulosis of the breast, a very rare underinvestigated lesion which must not be misinterpreted as a malignant epithelial tumour, such as adenoid cystic or signet-ring cell intraductal carcinoma, on histologic slides. The lesion is typically found in association with benign proliferative breast diseases. Prognosis is excellent.

[Neurofibromatosis and pregnancy. Considerations on a clinical case and review of the literature].

In this paper, starting from a case of neurofibromatosis adversely affecting pregnancy, the authors consider several interactions between pregnancy and Von Recklinhausen's diseases. The review of the literature emphasizes either an exacerbation of the maternal disease because of pregnancy, or the onset appearance of serious complications such as sarcomatous degeneration of neurofibromas, activation of a silent pheochromocytoma, rupture of an aneurysm. Moreover, the effects of neurofibromatosis on the pregnancy cause an elevated risk of IUGR, pregnancy hypertension, abortion and stillbirth and oligohydramnios.

Effects of an antiprostaglandin drug on human fallopian tubes in vivo.

The Authors studied 17 patients with patent tubes, normal ovulation and Rubin's test results. In the following cycle, this test was repeated divided into two phases. The first followed the normal procedure; the second started 10' after the e.
