Serine 62 is a phosphorylation site in folliculin, the Birt–Hogg–Dubé gene product

AbstractRecently, it was reported that the product of Birt–Hogg–Dubé syndrome gene (folliculin, FLCN) is directly phosphorylated by 5′-AMP-activated protein kinase (AMPK). In this study, we identified serine 62 (Ser62) as a phosphorylation site in FLCN and generated an anti-phospho-Ser62-FLCN antibody. Our analysis suggests that Ser62 phosphorylation is indirectly up-regulated by AMPK and that another residue is directly phosphorylated by AMPK. By binding with FLCN-interacting proteins (FNIP1 and FNIP2/FNIPL), Ser62 phosphorylation is increased. A phospho-mimic mutation at Ser62 enhanced the formation of the FLCN–AMPK complex. These results suggest that function(s) of FLCN–AMPK–FNIP complex is regulated by Ser62 phosphorylation.Structured summaryMINT-7298145, MINT-7298166: Flcn (uniprotkb:Q76JQ2) physically interacts (MI:0915) with AMPK alpha 1 (uniprotkb:P54645) by anti tag coimmunoprecipitation (MI:0007)MINT-7298267: AMPK alpha 1 (uniprotkb:Q13131) phosphorylates (MI:0217) tsc2 (uniprotkb:P49816) by protein kinase assay (MI:0424)MINT-7298182: FNIP1 (uniprotkb:Q8TF40) physically interacts (MI:0915) with Flcn (uniprotkb:Q76JQ2) by anti tag coimmunoprecipitation (MI:0007)MINT-7298132: AMPK alpha 1 (uniprotkb:Q13131) phosphorylates (MI:0217) Flcn (uniprotkb:Q76JQ2) by protein kinase assay (MI:0424)MINT-7298229: FNIPL (uniprotkb:Q9P278) physically interacts (MI:0915) with Flcn (uniprotkb:Q76JQ2) by anti tag coimmunoprecipitation (MI:0007

Person identification is one of the most important problems fo highly advanced present computer system for its security. It is absolutely necessary to keep off trespassers at the computer room. the materials room. etc.. Fingerprint is usually used for gate security because it has the highest reliability for personal identification. but it has fear to infringe on privacy. In this paper, a new gate security method using the length of joints of hand fingers is proposed and the result of fundamental experiment using 50 person\u27s data is shown. Since these features have not so high reliability as fingerprint. it has little faer to infringe on privacy. This method consists of two ways. that is. the first is identification by similarity degree, second is identification by Euclid distance. From the result of the experiment. it can be said that the probability of keeping off the trespassers is 84.2 (%) when the proposed method is used for gate security. If the method is used together with an ID card and a password. very high reliability can be obtained

Upper arm central venous port implantation: a 6-year single institutional retrospective analysis and pictorial essay of procedures for insertion.

The requirement of central venous (CV) port implantation is increasing with the increase in the number of cancer patients and advancement in chemotherapy. In our division, medical oncologists have implanted all CV ports to save time and consultation costs to other departments. Recently, upper arm implantation has become the first choice as a safe and comfortable method in our unit. Here we report our experience and discuss the procedure and its potential advantages.All CV port implantations (n = 599) performed in our unit from January 2006 to December 2011 were analyzed. Procedural success and complication rates between subclavian and upper arm groups were compared.Both groups had similar patient characteristics. Upper arm CV port and subclavian implantations were equivalently successful and safe. Although we only retrospectively analyzed data from a single center, the upper arm group had a significantly lower overall postprocedural complication rate than the subclavian group. No pneumothorax risk, less risk of arterial puncture by ultrasound, feasibility of stopping potential arterial bleeding, and prevention of accidental arterial cannulation by targeting the characteristic solitary basilic vein were the identified advantages of upper arm CV port implantation. In addition to the aforementioned advantages, there is no risk of "pinch-off syndrome," possibly less patient fear of manipulation, no scars on the neck and chest, easier accessibility, and compatibility with the "peripherally inserted central catheter" technique.Upper arm implantation may benefit clinicians and patients with respect to safety and comfort. We also introduce our methods for upper arm CV port implantation with the videos

Preparation.

<p>(<b>A</b>) <b>Minimum specific materials for the procedure.</b> In this kit, a CV port/catheter, a dilator sheath, and a guide wire are supplied. For venipuncture, we use common peripheral intravenous catheters with appropriate lengths and gauge sizes through which a guide wire can be passed. In this kit, an 18-gauge needle is sufficient. In case of “Seldinger technique”-based kits, a 20- or 22-gauge needle might be sufficient because those guide wires are usually thinner than “peel-off sheath”-based kits. Further, commonly used materials such as surgical caps, masks, eye protection, sterile gloves, gowns, drapes, disinfectant sponges, gauzes, sutures with needles, scalpels, anesthetic syringes, and 1% or 2% lidocaine anesthetic solutions are also required (not shown). (<b>B</b>) <b>Arm position.</b> The patient should be asked to lie down in the supine position, which allows the upper limb to abduct, upper arm to rotate outward, forearm to supinate, and medial side of the arm to be upward for better demonstration of the basilic vein. The elbow should not be bent, and the forearm should not be pronated. (<b>C</b>) <b>Tips for applying the probe with the correct angle.</b> The probe should be applied at the correct angle.</p

Port Implantation.

<p>(<b>A</b>) <b>Skin incision.</b> A scalpel should be used to make a skin incision from 2 cm to the right to 2 cm to the left of the puncture point. This incision should be used later as the entrance for making a subcutaneous pocket with a forceps. (<b>B</b>) <b>Making a slit between the skin and wire.</b> The connective tissues between the skin and wire should be cut with a scalpel to make a slit a few millimeters long over the wire in the puncture point. (<b>C</b>) <b>The purpose of a slit.</b> Without this step, the catheter route will be shallower from the skin surface; subsequently, the risk of catheter exteriorization will increase.</p
