Finding Safety in Numbers with Secure Allegation Escrows

For fear of retribution, the victim of a crime may be willing to report it only if other victims of the same perpetrator also step forward. Common examples include 1) identifying oneself as the victim of sexual harassment, especially by a person in a position of authority or 2) accusing an influential politician, an authoritarian government, or ones own employer of corruption. To handle such situations, legal literature has proposed the concept of an allegation escrow: a neutral third-party that collects allegations anonymously, matches them against each other, and de-anonymizes allegers only after de-anonymity thresholds (in terms of number of co-allegers), pre-specified by the allegers, are reached. An allegation escrow can be realized as a single trusted third party; however, this party must be trusted to keep the identity of the alleger and content of the allegation private. To address this problem, this paper introduces Secure Allegation Escrows (SAE, pronounced "say"). A SAE is a group of parties with independent interests and motives, acting jointly as an escrow for collecting allegations from individuals, matching the allegations, and de-anonymizing the allegations when designated thresholds are reached. By design, SAEs provide a very strong property: No less than a majority of parties constituting a SAE can de-anonymize or disclose the content of an allegation without a sufficient number of matching allegations (even in collusion with any number of other allegers). Once a sufficient number of matching allegations exist, the join escrow discloses the allegation with the allegers' identities. We describe how SAEs can be constructed using a novel authentication protocol and a novel allegation matching and bucketing algorithm, provide formal proofs of the security of our constructions, and evaluate a prototype implementation, demonstrating feasibility in practice.Comment: To appear in NDSS 2020.

ANTIDIABETIC EFFECTS OF [10]-GINGEROL IN STREPTOZOTOCIN- AND HIGH-FAT DIET-INDUCED DIABETIC RATS

Objective: India is the “diabetes capital of the world” with 62.4 million Indians having type 2 diabetes in 2011. A major risk factor for insulin resistance is obesity, which is generally caused by regular physical inactivity and high-fat diet (HFD). Obesity and diabetes are closely related to each other as about 80% of diabetics are obese. Obesity is a common finding in type 2 diabetes. The objective of the study was to investigate the antidiabetic effects of [10]-gingerol in streptozotocin (STZ)- and HFD-induced diabetic rats. Methods: Wistar rats were used for the study. Animals were divided into six groups. The six groups in this study were, Group I (normal control), Group II (diabetic control), Group III (glibenclamide at 5 mg/kg p.o.), Group IV (orlistat at 60 mg/kg p.o.), Group V ([10]-gingerol at 15 mg/kg p.o.), and Group VI [10]-gingerol (30 mg/kg p.o.), respectively. The antidiabetic activity was assessed using blood glucose level, body weight, and various biochemical parameters such as serum total cholesterol (TC) level, triglyceride (TG) level, high-density lipoproteins (HDLs), total protein (TP), serum alanine transaminase, and aspartate aminotransferase (serum glutamic-oxaloacetic transaminase), respectively. Results: [10]-gingerol exhibited an antidiabetic effect by significantly decreased the level of blood glucose, body weight, TC, TG, TP, and increase HDL. The results of the study demonstrated that the treatment with [10]-gingerol significantly (p<0.05) and dose dependently prevented STZ- and HFD-induced diabetic rats. Conclusions: The findings of the study suggest that [10]-gingerol possesses potential antidiabetic activity as it lowers serum glucose level

Motion of falling object

A simple setup was assembled to study the motion of an object while it falls. The setup was used to determine the instantaneous velocity, terminal velocity and acceleration due to gravity. Also, since the whole project was done within $20 it can easily be popularized.Comment: 11 pages, 4 figur

Dapsone induced photosensitivity in Indian women: a rare case

Dapsone, a potent antileprotic anti-inflammatory drug is used in treatment and prophylaxis of many dermatological and non dermatological conditions. Cutaneous adverse reactions to dapsone are uncommon ranging from mild maculopapular rash to fatal toxic epidermal necrolysis. We report here a case of 40-year-old, housewife treated for leprosy with paucibacillary multi drug therapy who presented with red itchy skin lesions over exposed areas of skin which worsened on exposure to sunlight. The patient was diagnosed as a case of dapsone-induced photosensitive dermatitis which was confirmed by improvement of symptoms on withdrawal of dapsone and recurrence of similar lesions on rechallenge with dapsone in reduced dose. Photosensitivity as adverse drug reaction to dapsone is rare and very few reports are available in the literature.

Atypical presentation of intra-articular osteochondroma of knee in adolescent- case report

Osteochondroma is most common benign bone tumor around knee joint. They occur during the period of growth, grows away from joint line and rarely responsible for mechanical symptoms. This paper reports a rare presentation of intra-articular osteochondroma in knee with mechanical instability symptoms, mild to moderate pain and swelling of knee joint. Patient was 20 years old male and misdiagnosed as chronic nonspecific synovitis, tubercular arthritis and anterior cruciate ligament tear of knee. We assessed him clinically and radiologically and diagnosis was established based on MRI and arthroscopy. He was treated by open excision of tumor, and patients recover uneventfully. Instability of knee joint in this case can be attributed due to rough surface of osteochondroma just beneath lower attachment of patellar tendon

Comparison of Landmark Versus ECG-Guided Technique for Correct Insertion of Central Venous Catheter in Paediatric Patients Undergoing Cardiothoracic Surgery

Background: Central venous catheters are inserted in internal jugular vein during cardiac surgeries in all patients. However, the length of the catheter should be correctly estimated and the tip of the CVC should be correctly placed to avoid various complications.  The primary objective of this study is to compare anatomical landmark technique versus using ECG-guided technique for the correct insertion length of the Central Venous Catheter. Methods: Prospective, randomized, interventional study was conducted on 72 patients of <12 years age. Patients were randomly allotted to two groups of 36 patients each (landmark and ECG). After induction, CVC cannulation was performed using either of the techniques in right IJV in all patients. Correct position of CVC was checked by obtaining post operative chest X rays in all patients. CVC tip position within 0.5cm above/below or at carina was considered as correct position. Using student t-tests and Chi square-tests analyses were performed. Results: In landmark group, CVC was positioned correctly in 22(61.11%) out of 36 patients as compared to 33 (91.67%) in the ECG group, (P = 0.006). The mean depth of CVC insertion was 9.05±1.66 and 8.26±1.41 in the landmark and ECG group respectively (P= 0.032). The landmark group had 12 (33.33%) patients with complications during the procedure, as compared to 3(8.33%) in the ECG-guided group, (P = 0.020). Conclusion: ECG-guided CVC insertion, a simple bedside technique was found more accurate with lesser complications for CVC tip placement than the landmark technique. ECG-guided CVC placement is therefore relatively more accurate, efficient, and safe
