Effects of Stephania hainanensis alkaloids on MSU-induced acute gouty arthritis in mice
BMC Complementary Medicine and Therapies, 2021 Background Gout is initiated by the precipitation of monosodium urate (MSU) crystals within the joints and soft tissues, and it can eventually cause acute or chronic arthritis.

Finding Collisions against 4-Round SHA-3-384 in Practical Time
IACR Transactions on Symmetric Cryptology, 2022 The Keccak sponge function family, designed by Bertoni et al. in 2007, was selected by the U.S. National Institute of Standards and Technology (NIST) in 2012 as the next generation of Secure Hash Algorithm (SHA-3).

Malicious Hashing: Eve’s Variant of SHA-1 [PDF]
, 2014 We present collisions for a version of SHA-1 with modified constants, where the colliding payloads are valid binary files. Examples are given of colliding executables, archives, and images. Our malicious SHA-1 instances have round constants that differ from the original ones in only 40 bits (on average). Modified versions of cryptographic standards are

BMC Musculoskeletal Disorders, 2013 Backgroud While serum levels of hyarulonic acid (sHA) is known to be useful for a burden of disease biomarker in knee OA, it is far from practical. The reference intervals must be established for biomarkers to be useful for clinical interpretation.

Indonesian Journal of Electrical Engineering and Computer Science, 2018 Hashes are used to check the integrity of data. This paper modified SHA-1 by incorporating mixing method in every round for better diffusion. The modification increased the hash output to 192-bits. Increasing the output increases the strength because breaking the hash takes longer.

Algebraic Cryptanalysis of 58-Round SHA-1 [PDF]
, 2007 In 2004, a new attack against SHA-1 has been proposed by a team leaded by Wang [15]. The aim of this article is to sophisticate and improve Wang’s attack by using algebraic techniques. We introduce new notions, namely semi-neutral bit and adjuster and propose then an improved message modification technique based on algebraic techniques.

Exploiting an HMAC-SHA-1 Optimization to Speed up PBKDF2 [PDF]
IEEE Transactions on Dependable and Secure Computing, 2020 PBKDF2 [1] is a well-known password-based key derivation function. In order to slow attackers down, PBKDF2 introduces CPU-intensive operations based on an iterated pseudorandom function (in our case HMAC-SHA-1). If we are able to speed up a SHA-1 or an HMAC implementation, we are able to speed up PBKDF2-HMAC-SHA-1.
