Background: Leptin is a hormone which is secreted by the adipocytes. In the circulation, leptin levels are directly proportional to the body fat percentage. Studies have shown that higher leptin levels are associated with an increased risk of hypertension after adjusting for body mass index (BMI).

- The TAOK proteins are important kinases involved in various cellular functions and are linked to neurodevelopmental disorders (NDDs) like those caused by TAOK1 and TAOK2 variants.
- A study analyzed clinical and genetic data from individuals with these variants, revealing that TAOK1 variants lead to significant neurodevelopmental issues and some novel characteristics, while TAOK2 variants are tied to neurodevelopmental abnormalities, autism, and obesity.
- This research expands the understanding of these disorders by presenting the largest cohort of individuals with TAOK1-NDD and identifying new variants and phenotypes associated with both TAOK1 and TAOK2.
We show that quantum entanglement can provide an exponential advantage in learning properties of a bosonic continuous-variable (CV) system. The task we consider is estimating a probabilistic mixture of displacement operators acting on n bosonic modes, called a random displacement channel. We prove that if the n modes are not entangled with an ancillary quantum memory, then the channel must be sampled a number of times exponential in n in order to estimate its characteristic function to reasonable precision; this lower bound on sample complexity applies even if the channel inputs and measurements performed on channel outputs are chosen adaptively or have unrestricted energy.

Although it is possible to churn cream on a small scale, matching the microstructure of butter is a challenge. A 2-step churning process was introduced with the application of a kitchen mixer.

We investigated whether the kidney parenchyma fat content and kidney sinus fat volume would be higher in persons with T2D and CKD.
Methods: Cross-sectional study including 29 controls, 27 persons with T2D and no CKD, and 48 persons with T2D and early CKD (urine albumin creatinine ratio (UACR) ≥ 30 mg/g).
