Micro-ultrasound experience and clinically significant prostate cancer detection: a center-level analysis of the optimum randomized trial
Abstract Micro-ultrasound real-time imaging technology is increasingly performed for prostate biopsy. While a learning curve is expected, the effect of operator experience on clinically significant prostate cancer (csPCa) detection has not been clearly defined.
Bridging the Cybersecurity Talent Gap
There’s no doubt about it. Cybersecurity incidents are rising. In 2024, the FBI reported a 9% increase in ransomware complaints targeting critical U.S. infrastructure sectors, such as healthcare, manufacturing and government facilities. The cost of these breaches is also increasing. A report from IBM found that the average cost of a data breach in 2024 totaled $4.88 M. Despite advancements in cybersecurity prevention and detection, bad actors will always look for another way to commit cybercrimes.
Altered Mitochondrial Respiration Is Associated With Loss of Nuclear‐Encoded OXPHOS Genes in Parasitic Broomrapes
1 Introduction Mitochondria fuel energy metabolism for nearly all eukaryotes, including plants. Chemical energy is converted to ATP via a series of orchestrated oxidative phosphorylation enzymes (OXPHOS) and accessory proteins that transport electrons, pump protons, and ultimately convert ADP to ATP.
Mini-bacterioferritins: Structural insight into a new type of ferritin-like protein from an anaerobic methane-oxidising archaeon
Abstract Ferritins are ubiquitous among life forms, as they are essential for iron homeostasis. Here, we unveiled a novel member of the ferritin family, baptised mini-bacterioferritin. The characterised mini-bacterioferritin was isolated from a microbial enrichment dominated by the methanotrophic archaeon "Candidatus Methanoperedens" BLZ2. Its atomic resolution crystal structure reveals a 12-mer assembly with a diiron ferroxidase centre located within a four-helix bundle.
Nitric oxide-forming nitrite reductases in the anaerobic ammonium oxidizer Kuenenia stuttgartiensis
Abstract Anaerobic ammonium-oxidizing (anammox) bacteria contribute to the global nitrogen cycle by removing fixed nitrogen from the environment. They do so via the anaerobic oxidation of ammonium to dinitrogen gas, with nitrite as terminal electron acceptor. The first step in this so-called anammox reaction is the conversion of nitrite to nitric oxide by nitrite reductase.
Recombination and retroprocessing in broomrapes reveal a universal roadmap for mitochondrial evolution in heterotrophic plants
Abstract The altered life history strategies of heterotrophic organisms often leave a profound genetic footprint on energy metabolism related functions. In parasitic plants, the reliance on host-derived nutrients and loss of photosynthesis in holoparasites have led to highly degraded to absent plastid genomes, but its impact on mitochondrial genome (mitogenome) evolution has remained controversial.
Altered mitochondrial respiration is associated with loss of nuclear-encoded OXPHOS genes in parasitic broomrapes
Abstract Parasitic plants, characterized by their dependency on host organisms for nutrients, have displayed far-reaching alterations in physiology and genetics. While significant gene losses and relaxed selection have been documented in the nuclear and plastid genomes, how parasitism impacts the molecular evolution and function of mitochondria has remained controversial.
On the importance of sequence alignment inspections in plastid phylogenomics – an example from revisiting the relationships of the water‐lilies
Introduction Nymphaeaceae are a near-cosmopolitan family of flowering plants that comprise approximately 75 species of aquatic herbs in five distinct genera (i.e. Barclaya, Euryale, Nuphar, Nymphaea and Victoria; Borsch et al., 2008; Löhne et al., 2009). Nymphaea, commonly referred to as “water-lilies,” represents the largest and most widely distributed genus of the family.
Out of Place: Three Eurasian Taxa Shed Light on Origin of Thermopsideae in North America
Abstract The North American Thermopsideae, a monophyletic group comprising the North American endemic Baptisia, and the paraphyletic Eurasian-North American disjunct Thermopsis, is nested within the Sophoreae (Fabaceae: Papilionoideae). Previous phylogenetic studies have identified two East Asian taxa within the North American Thermopsideae, suggesting two independent dispersal events between North America-East Asia.
Advancing tuberculosis management: the role of predictive, preventive, and personalized medicine
1. Introduction Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis (Mtb). The World Health Organization (WHO) formulated the End TB Strategy to achieve the ultimate eradication of TB. The strategy gained approval in 2014 from the 67th World Health Assembly and aims to terminate the global TB epidemic by 2035 (WHO, 2021).
Time-resolved transcriptomic and proteomic profiling of Heyndrickxia coagulans during NaOH-buffered L-lactic acid production
1 Introduction Lactic acid (LA), also known as dihydroxypropionic acid with a molecular formula of C3H6O3, is one of the primary organic acids globally (Juturu and Wu, 2016; Huang et al., 2021; Rawoof et al., 2021). Its versatile applications encompass diverse industries, including food, chemical, and pharmaceutical sectors.
Microbial degradation of plant toxins
INTRODUCTION The Plantae kingdom includes organisms ranging from minuscule mosses to massive trees. Yet, regardless of their size, all plants produce a variety of low- and high-molecular-weight metabolites. According to their function, they have been classified into three categories: phytohormones (PHs), and phytochemicals, which include plant primary metabolites (PPMs), and specialized molecules or plant secondary metabolites (PSMs).

The establishment of an Equitable Access (EA) program means every student will have the same opportunity and tools needed for success.
Equitable Access Improves Course Completion and Student Success
Course completion and student success percentages are significantly increased at higher education institutions that have introduced Equitable Access (EA) programs, especially two-year institutions. The establishment of an EA program means every student will have the same opportunity and tools needed for success. The unique financial challenges faced by every student act as barriers to student success and retention.
Equitable access can improve course completion and student success
“There is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things.” –Niccolo Machiavell Course completion and student success percentages are significantly increased at higher education institutions that have introduced Equitable Access (EA) programs, especially two-year institutions.
MS2Query: reliable and scalable MS2 mass spectra-based analogue search - Nature Communications
Workflow MS2Query MS2Query builds on the improvements of two machine learning-based methods, developed to predict chemical similarity from MS2 mass spectral pairs; Spec2Vec30 and MS2Deepscore32. These methods perform especially well at predicting chemical similarity for molecules that are similar but are chemically not exact matches. This makes Spec2Vec and MS2Deepscore very suitable for an analogue search.

An exercise-inducible metabolite that suppresses feeding and obesity - Nature
Abstract Exercise confers protection against obesity, type 2 diabetes and other cardiometabolic diseases1,2,3,4,5. However, the molecular and cellular mechanisms that mediate the metabolic benefits of physical activity remain unclear6. Here we show that exercise stimulates the production of N-lactoyl-phenylalanine (Lac-Phe), a blood-borne signalling metabolite that suppresses feeding and obesity.

CinA mediates multidrug tolerance in Mycobacterium tuberculosis - Nature Communications
Abstract The ability of Mycobacterium tuberculosis (Mtb) to resist and tolerate antibiotics complicates the development of improved tuberculosis (TB) chemotherapies. Here we define the Mtb protein CinA as a major determinant of drug tolerance and as a potential target to shorten TB chemotherapy. By reducing the fraction of drug-tolerant persisters, genetic inactivation of cinA accelerated killing of Mtb by four antibiotics in clinical use: isoniazid, ethionamide, delamanid and pretomanid.
Opinion: Grady Hospital’s COVID-19 plea — stay the course!
By Robert Jansen In the next few weeks, Georgia is expected to face the peak of this round of COVID-19 infections. It will tax the capacity of our hospitals, test the patience of a public weary of sheltering at home and challenge the stamina of medical professionals who have already worked to the point of exhaustion. But we will get through it.
