Lentera UMKM-Pendampingan UMKM Regie’s Production Berbasis Teknologi di Masa Pandemi Covid-19 IEEE HAC & SIGHT Project

Micro, Small and Medium Enterprises (UMKM) is one of the drivers of development and the Indonesian economy. In the midst of the Covid19 pandemic, MSMEs are challenged to exist and survive all forms of existing threats. Starting from the decline in people's purchasing power to result in the fall of MSMEs due to this uncertain condition. In addition, health threats are also not spared MSME players serve and transact with buyers, physical contact is one of the causes of transmission of the Covid19 virus. The formulation of the problem of community service is how MSME actors can market their products during a pandemic and can take advantage of platforms or technology so that there is no need to make direct contact with buyers. The purpose of this community service is to provide continuous coaching in an integrated manner with the help of recommended technology (Halosis, Canva, Web lantera-umkm.com).   Usaha Mikro Kecil dan Menengah (UMKM) merupakan salah satu penggerak pembangunan dan perekonomian Indonesia.

Effects of warm-up before stretching on flexibility and torque development in elderly

The purpose of the study was to analyze the effect of warm up exercises on flexibility and torque development of elderly subjects submitted to a protocol of hamstring muscles stretching. 28 subjects (9 men and 19 women), aged 66.4±6 years, volunteered for this study. Subjects were randomly divided into 2 protocols: a stretching protocol (group A) and a warm up and stretching protocol (group B). Both groups received the intervention for 4 weeks, with three sessions per week, consisting of 6 bouts of active stretching lasting 30 seconds. Subjects were evaluated on selection (T1), immediately before the intervention (T2), immediately after (T3) and a month after (T4) the intervention period for measures of knee extension range of motion (ROM) and angle with a goniometer and for active and passive peak torque (Nm s-1) at 60°/s and 2°/s respectively using a isokinetic dynamometer. Anova Two-Way and a post hoc analysis using the Tukey’s test were applied to test the differences between and within groups. Both groups presented reduction of the knee extension range of motion deficit (p=0.001), increase of the active peak torque flexor in eccentric (p=0.003) and concentric (p=0.015) phases, and reduction of the peak torque angle of the knee flexors in the eccentric phase (p=0.046) when comparing T3 with T2 for both groups, without significant difference between groups. The passive peak torque did not vary significantly (p\u3e0.05) between the evaluations. The pre-exercise warm up was unable to elicit differences in flexibility and torque development of the hamstrings in elderly subjects

Magnetization Reversal by Electric-Field Decoupling of Magnetic and Ferroelectric Domains Walls in Multiferroic-Based Heterostructures

We demonstrate that the magnetization of a ferromagnet in contact with an antiferromagnetic multiferroic (LuMnO3) can be speedily reversed by electric field pulsing, and the sign of the magnetic exchange bias can switch and recover isothermally. As LuMnO3 is not ferroelastic, our data conclusively show that this switching is not mediated by strain effects but is a unique electric-field driven decoupling of the ferroelectric and ferromagnetic domains walls. Their distinct dynamics are essential for the observed magnetic switching

Multidrug resistance protein 1 localization in lipid raft domains and prostasomes in prostate cancer cell lines

Background: One of the problems in prostate cancer (CaP) treatment is the appearance of the multidrug resistance phenotype, in which ATP-binding cassette transporters such as multidrug resistance protein 1 (MRP1) play a role. Different localizations of the transporter have been reported, some of them related to the chemoresistant phenotype. Aim: This study aimed to compare the localization of MRP1 in three prostate cell lines (normal, androgen-sensitive, and androgen-independent) in order to understand its possible role in CaP chemoresistance. Methods: MRP1 and caveolae protein markers were detected using confocal microscopy, performing colocalization techniques. Lipid raft isolation made it possible to detect these proteins by Western blot analysis. Caveolae and prostasomes were identified by electron microscopy. Results: We show that MRP1 is found in lipid raft fractions of tumor cells and that the number of caveolae increases with malignancy acquisition. MRP1 is found not only in the plasma membrane associated with lipid rafts but also in cytoplasmic accumulations colocalizing with the prostasome markers Caveolin-1 and CD59, suggesting that in CaP cells, MRP1 is localized in prostasomes. Conclusion: We hypothesize that the presence of MRP1 in prostasomes could serve as a reservoir of MRP1; thus, taking advantage of the release of their content, MRP1 could be translocated to the plasma membrane contributing to the chemoresistant phenotype. The presence of MRP1 in prostasomes could serve as a predictor of malignancy in Ca
