The Quick Defense Personal Self-Defense System

Phyllidiella nigra is an organism that is suspected to have secondary metabolites because their ability to develop its self defense system by camouflage and using chemical compounds derived from their nature diet as deterrent against their predators. The purpose of this study was to isolate symbiotic bacterial derived from P. nigra, extracted and followed by, the antibacterial assays against Escherichia coli and Bacillus megaterium as well as the anti-UV assay. The results showed that the five isolates tested had an antibacterial activity with the highest average inhibition zone against E. coli DSM 498 bacteria, isolate 1 (14.67 mm), isolate 5 (14 mm), and against B. Megaterium DSM 32T bacteria, isolate 3 (13.33 mm). The three isolates which had the highest inhibition zone and P. nigra extract were tested for anti-UV assay using a UV-Vis Spectrophotometer. The results obtained isolate 3 has absorption of UV-A with the UV absorbtion maximum at λ 340 nm and P. nigra extract has absorption on UV-B radiation with UV absorption maximum at λ 290 nm. Key words: Nudibranchia, Bacteria, Anti-bacteial, Anti-UV Phyllidiella nigra merupakan organisme yang diduga memiliki metabolit sekunder karena mampu mengembangkan sistem pertahanan dirinya dengan cara kamuflase dan menggunakan senyawa kimia sebagai racun yang didapat dari makanannya. Tujuan dari penelitian ini yaitu mendapatkan isolat bakteri yang bersimbiosis dengan P. nigra, mendapatkan ekstrak dari baktri simbion, dan menguji antibakteri dan anti-UV ekstrak etil aseta bakteri simbion dengan metode difusi agar terhadap bakteri Escherichia coli dan Bacillus megaterium. Hasil penelitian didapatkan kelima isolat yang diuji memiliki aktivitas antibakteri dengan rerata zona hambat tertinggi terhadap bakteri E. coli DSM 498 yaitu isolat 1 (14,67 mm), isolat 5 (14 mm), dan terhadap baktri B. megaterium DSM 32T yaitu isolat 3 (13,33 mm). Ketiga isolat yang memiliki zona hambat tertinggi dan ekstrak P. nigra diujikan anti-UV menggunakan alat UV-Vis Spektrofotometer. Hasil yang didapat isolat 3 memiliki serapan terhadap radiasi sinar UV-A dengan puncak tertinggi pada λ 340 nm dan ekstrak P. nigra memiliki serapan terhadap radiasi sinar UV-B dengan puncak tertinggi berada pada λ 290 nm.

Abstract We isolated a cDNA representing a message that was strongly induced by injection with E. coli in Bombyx mori. The 2160 bp cDNA has an open reading frame of 644 amino acids and the deduced product a predicted molecular mass of 71 kDa. The cDNA sequence shared high homology with the transferrins known so far, and its deduced peptide had unique features of transferrins, that is, sites of cystein residues and iron binding. We suggest that the B. mori transferrin plays an important role in the self-defense system.

Nowadays, women and children safety is a prime issue of our society. The count of the victim is increasing day by day. In this paper, we are proposing a model which will develop a self defense system especially for women to ensure the safety and to protect themselves from present day physical harassments. We have used different sensors like the knock sensor, temperature sensor, 3-axis accelerometer. We have also used GPS which will help to detect the location of the device. GSM used in the model is used to send the alert message to predefined number, police station. We have proposed embedded microcontroller based device ARDUINO which will help to continuously monitor values of different sensors and GPS used in the device.

Background Experts of the Krav Maga (KM) self-defense system propose that KM techniques are based on simple body movements which are suggested to be learned rapidly and retained. This study investigated the acquisition, retention, and further improvement with additional training of two KM strike techniques among novice female practitioners: straight punch and defensive kick. Methods Sixteen healthy females (age: 23 ± 3.7 years) without any previous martial arts/self-defense experience volunteered to participate. All participants received an initial 30-min instruction session (AQ), taught by a certified KM instructor, where each technique was deconstructed into three checkpoints (defined as a component of the entire movement) for learning. Participants were divided into two groups, one of which received additional training. Several kinematic and kinetic measures were recorded at four timepoints: immediately before AQ, immediately after AQ, 5 days after AQ, and 12 days after AQ. Results Results suggest that both techniques were learned rapidly, as checkpoint performance was significantly improved after AQ. Kick velocity and impact force also increased significantly after AQ; however, these measures did not change after AQ for the punch technique. Additional training did not improve either punch or kick performance beyond that learned during AQ. Conclusion The findings from this study suggest that a single training session may be sufficient to learn and retain KM strike techniques relatively permanently; and the acquisition of the kick technique may lead to concomitant improvements in kick velocity and impact force.

Regulation Of Growth

SIRT1 inhibitors can reduce replication of many viruses with certain similar characteristics to those of Coronaviruses, while p53 protein is another important factor in down-regulation of growth. There are some molecules that inhibit Sirtuin 1 and 2, in addition to activate p53 protein, by means of regulation of the interactions used by Coronaviruses as self-defense mechanism, degradating it. Even mTOR signal will be regulate, as well as HIF-1α with the target genes and cytokines. Autophagy will be inhibited, being this compound like a lysosomotropic agent. By blocking virus growth and continuous replication, associating the already tested Antiviral medicines, Covid-19 could be eradicated.
