A Novel Probability-Based Logic-Locking Technique: ProbLock.

Integrated circuit (IC) piracy and overproduction are serious issues that threaten the security and integrity of a system. Logic locking is a type of hardware obfuscation technique where additional key gates are inserted into the circuit. Only the correct key can unlock the functionality of that circuit; otherwise, the system produces the wrong output.

New Insights into the Ultrastructure of Bioapatite After Partial Dissolution: Based on Whale Rostrum, the Densest Bone.

Mineral particles in bone are interlaced with collagen fibrils, hindering the investigation of bioapatite crystallites (BAp). This study utilized a special whale rostrum (the most highly mineralized bone ever recorded) to measure the crystallites of bone BAp via long-term dissolution in water. The BAp in the rostrum has a low solubility (6.

The effect of wilderness and medical training on injury and altitude preparedness among backcountry hikers in Rocky Mountain National Park.

Background: The purpose of this study was to document the correlation between medical and wilderness training with levels of preparedness for acute mountain sickness (AMS), illness, and injury among backcountry hikers.

Methods: We conducted a cross-sectional, convenience survey in Rocky Mountain National Park in July and August 2015. The study group consisted of 380 hikers who completed a written survey that collected information about demographics, wilderness experience, altitude experience, hiking equipment, communications devices, and trip planning.

Evidence Supporting a Lymphatic Endothelium Origin for Angiomyolipoma, a TSC2(-) Tumor Related to Lymphangioleiomyomatosis.

Angiomyolipoma (AML) is a tumor closely related to lymphangioleiomyomatosis (LAM). Both entities are characterized by the proliferation of smooth muscle actin and melanocytic glycoprotein 100 (recognized by antibody HMB-45)-positive spindle-shaped and epithelioid cells. AML and LAM are etiologically linked to mutations in the tsc2 and tsc1 genes in the case of LAM.

A method for efficient expression of Pseudomonas aeruginosa alginate lyase in Pichia pastoris.

As an eco-friendly biocatalyst for alginate hydrolysis, bacteria-derived alginate lyase (AlgL) has been widely used in research and industries to produce oligosaccharides. However, the cost of AlgL enzyme production remains high due to the low expression and difficulty in purification from bacterial cells. In this study we report an effective method to overexpress the Pseudomonas aeruginosa AlgL (paAlgL) enzyme in Pichia pastoris.

Novel RNA-binding protein P311 binds eukaryotic translation initiation factor 3 subunit b (eIF3b) to promote translation of transforming growth factor β1-3 (TGF-β1-3).

P311, a conserved 8-kDa intracellular protein expressed in brain, smooth muscle, regenerating tissues, and malignant glioblastomas, represents the first documented stimulator of TGF-β1-3 translation in vitro and in vivo. Here we initiated efforts to define the mechanism underlying P311 function. PONDR® (Predictor Of Naturally Disordered Regions) analysis suggested and CD confirmed that P311 is an intrinsically disordered protein, therefore requiring an interacting partner to acquire tertiary structure and function.

In pulmonary lymphangioleiomyomatosis expression of progesterone receptor is frequently higher than that of estrogen receptor.

Lymphangioleiomyomatosis (LAM) of the lung is a rare low-grade malignancy affecting primarily women of childbearing age. LAM is characterized by the proliferation of SMA and HMB-45 positive spindle-shaped and epithelioid cells throughout the lung in the form of discrete lesions causing cystic destruction and ultimately respiratory insufficiency. LAM occurs sporadically or in patients with tuberous sclerosis complex (TSC) and is etiologically linked to mutations in the TSC1 and TSC2 genes.
