Disentangling collective coupling in vibrational polaritons with double quantum coherence spectroscopy.

Vibrational polaritons are formed by strong coupling of molecular vibrations and photon modes in an optical cavity. Experiments have demonstrated that vibrational strong coupling can change molecular properties and even affect chemical reactivity. However, the interactions in a molecular ensemble are complex, and the exact mechanisms that lead to modifications are not fully understood yet.

Transcriptomic alterations in the ovine caruncular endometrium due to imbalanced nutrition and FSH-induced ovarian hyperstimulation.

Background: Imbalanced diet and exogenous gonadotrophins affect uterine function and morphology. In sheep, FSH-induced superovulation alters implantation-related gene expression, influenced by both treatment and diet. In this study, we used deep RNA sequencing (NGS, RNA-Seq) to expand our understanding of these effects on the caruncular endometrium.

Preoperative and Postoperative Arterial Adaptation in Patients with Acute Aortic Dissection.

Spinal cord ischemia is one of the most serious complications after an aortic repair. To date, there is no evidence for arterial changes during an aortic dissection or for the observation of such arteries after an aortic repair. The aim of this study was to compare spinal-cord-supplying arteries in patients with an acute aortic dissection, preoperatively and postoperatively, with patients without an acute aortic dissection.

The role of Impella in the pre-procedural management of post-infarct ventricular septal defect: a systematic review.

Objectives: Post-infarct ventricular septal defect is a rare but devastating complication. Delayed treatment offers better outcomes than emergency surgery, but when acute cardiogenic shock or unstable haemodynamics occur, temporary mechanical circulatory support may be needed to stabilize patients until treatment. The aim of our systematic review was to assess the outcomes of using Impella in this setting.

Male adoption in the black and gold howler monkey (Alouatta caraya).

Infant adoption is an association that occurs between an adult individual and a dependent infant and occurs most often when lactating females care for a nutritionally dependent infant that is not her offspring. Adult females are often involved in adoption; while, direct infant care by males occurs in less than 5% of all mammalian species. We report the first record of adoption by wild male adults of Alouatta caraya, a platyrrhine primate species that does not typically participate in parental care.

Supercritical density fluctuations and structural heterogeneity in supercooled water-glycerol microdroplets.

Recent experiments and theoretical studies strongly indicate that water exhibits a liquid-liquid phase transition (LLPT) in the supercooled domain. An open question is how the LLPT of water can affect the properties of aqueous solutions. Here, we study the structural and thermodynamic properties of supercooled glycerol-water microdroplets at dilute conditions (χ = 3.

Ultrafast Mapping of Electronic and Nuclear Structure in the Photo Dissociation of Nitrogen Dioxide.

We investigate the photoinduced dissociation reaction of NO → NO + O upon electronic excitation of the X̃A (D) to the ÃB (D) state by femtosecond X-ray absorption spectroscopy at the nitrogen K-edge. We obtain key insight into the chemical bond breaking event and its associated electronic structural dynamics. Calculations of the photoinduced reaction allow to assign the transient absorption features at time scales of 10-50 fs to wave packet motions in the excited D and ground D states, followed by the formation of the NO photoproduct with a 255 ± 23 fs time constant.

The Frozen Elephant Trunk Procedure-8 Years of Experience from Poland.

The frozen elephant trunk method combines the implantation of a Dacron prosthesis with a self-expanding stent graft, which allows for complex repairs of the aortic arch and thoracic aorta in one procedure. Despite the advantages of hybrid treatment for aortic arch aneurysms, in Poland, only a few such surgeries are performed annually compared to in Western countries. The aim of this study was to demonstrate the 8-year outcomes of treatment at the center where the Aortic Team operates, which is one of the centers in Poland with the most extensive experience in hybrid FET treatment.

Canine Mammary Tumours (CMTs) exploit mitochondrial cholesterol for aggressive reprogramming.

In human breast cancer the mitochondrial translocator protein (TSPO) aids pro-survival cellular response by facilitating the formation of mitochondrial contact sites with the nucleus termed Nucleus Associated Mitochondria (NAM). Here, we show that TSPO positively associates with the aggressiveness of tissues and cells isolated from Canine Mammary Tumours (CMTs). TSPO is also readily upregulated in reprogrammed mammary tumour cells following long-term deprivation of oestrogen or exposure to the endocrine chemotherapeutic (ET) agent Tamoxifen.

Diversity of Anaplasmataceae Transmitted by Ticks (Ixodidae) and the First Molecular Evidence of and Anaplasma boleense in Paraguay.

Anaplasmataceae bacteria are emerging infectious agents transmitted by ticks. The aim of this study was to identify the molecular diversity of this bacterial family in ticks and hosts, both domestic and wild, as well as blood meal sources of free-living ticks in northeastern Paraguay. The bacteria were identified using PCR-HRM, a method optimized for this purpose, while the identification of ticks and their blood meal was performed using conventional PCR.

Human-driven breakdown of predator-prey interactions in the northern Adriatic Sea.

Long-term baseline data that allow tracking how predator-prey interactions have responded to intensifying human impacts are often lacking. Here, we assess temporal changes in benthic community composition and interactions between drilling predatory gastropods and their molluscan prey using the Holocene fossil record of the shallow northern Adriatic Sea, which is characterized by a long history of human transformation. Molluscan assemblages differ between the Isonzo and Po prodelta, but both show consistent temporal trends in the abundance of dominant species.

Distinguishing Organomagnesium Species in the Grignard Addition to Ketones with X-Ray Spectroscopy.

The addition of Grignard reagents to ketones is a well-established textbook reaction. However, a comprehensive understanding of its mechanism has only recently begun to emerge. X-ray spectroscopy, because of its high selectivity and sensitivity, is the ideal tool for distinguishing between an ensemble of competing pathways.

What Can We Learn from the Scalp Hair's Trace Element Content? The Relationship with the Advancement of Coronary Artery Disease.

: Multiple risk factors for coronary artery disease have been identified without answering one of the leading questions related to the extent of the involvement of the epicardial arteries. Trace elements are involved in various stages of atherosclerotic lesion formation and may play a significant role in the advancement of coronary artery disease. : A total of 157 (92 (59%) men and 65 (41%) women) patients with a median age of 71 (65-75) years presenting with chronic coronary syndrome were enrolled in the prospective single-center analysis.

Short- and long-term outcomes in isolated vs. hybrid thoracoscopic ablation in patients with atrial fibrillation: a systematic review and reconstructed individual patient data meta-analysis.

Aims: Both isolated thoracoscopic and hybrid thoracoscopic atrial fibrillation (AF) ablation techniques have demonstrated favourable outcomes in the management of patients with (long-standing) persistent AF, as compared with catheter ablation. However, it is currently unknown whether there is a difference in short- and long-term outcomes when comparing these two minimally invasive surgical AF ablation procedures. Therefore, a systematic review and meta-analysis were performed to investigate these two techniques, with a specific emphasis on long-term freedom from atrial tachyarrhythmias (ATAs).

Advanced piperazine-containing inhibitors target microbial β-glucuronidases linked to gut toxicity.

The gut microbiome plays critical roles in human homeostasis, disease progression, and pharmacological efficacy through diverse metabolic pathways. Gut bacterial β-glucuronidase (GUS) enzymes reverse host phase 2 metabolism, in turn releasing active hormones and drugs that can be reabsorbed into systemic circulation to affect homeostasis and promote toxic side effects. The FMN-binding and loop 1 gut microbial GUS proteins have been shown to drive drug and toxin reactivation.

Long-Term Nitrogen Dioxide Exposure as a Possible 5-Year Mortality Risk Factor in Diabetic Patients Treated Using Off-Pump Surgical Revascularization-A Retrospective Analysis.

: There is mounting evidence that diabetic-related cardiac metabolism abnormalities with oxidative stress and inflammatory mechanism activation align with the functional impairments that result in atherosclerotic lesion formation. Among the possible non-traditional coronary lesion risk factors, environmental exposure may be significant, especially in diabetic patients. : A total of 140 diabetic patients (115 (82%) males and 25 (18%) females) with a mean age of 65 (60-71) underwent surgical revascularization due to multivessel coronary disease.

Are Hair Scalp Trace Elements Correlated with Atherosclerosis Location in Coronary Artery Disease?

Coronary artery disease is among the leading current epidemiological challenges. The genetic, clinical, and lifestyle-related risk factors are well documented. The reason for specific epicardial artery locations remains unsolved.

Drug-Eluting Balloons and Drug-Eluting Stents in Diabetic Patients Undergoing Percutaneous Coronary Intervention Due to Restenosis-DM-Dragon Registry.

: The rate of in-stent restenosis (ISR) is decreasing; however, it is still a challenge for contemporary invasive cardiologists. Therapeutic methods, including drug-eluting balloons (DEBs), intravascular lithotripsy, excimer laser coronary atherectomy, and imaging-guided percutaneous coronary intervention (PCI) with drug-eluting stents (DES), have been implemented. Patients with diabetes mellitus (DM) are burdened with a higher risk of ISR than the general population.

The effects of the activation of TLR2/TLR1 on in vitro angiogenesis in an immortalized ovine luteal endothelial cell line.

In Brief: Activation of TLR2/TLR1 alters in vitro formation of capillary-like structures and induces inflammatory processes in ovine luteal endothelial (OLENDO) cells.

Abstract: Postpartum bacterial infections of the uterus affect uterine physiology and ovarian activity, causing fertility problems. The outer membrane component of Gram-negative bacteria, lipopolysaccharide, is involved in the initiation of the local inflammatory processes, and other bacterial toxins, particularly lipopeptides, have also been shown to be potent cytokine inducers, acting via Toll-like receptor-2 (TLR2).

Extending the Tavis-Cummings model for molecular ensembles-Exploring the effects of dipole self-energies and static dipole moments.

Strong coupling of organic molecules to the vacuum field of a nanoscale cavity can be used to modify their chemical and physical properties. We extend the Tavis-Cummings model for molecular ensembles and show that the often neglected interaction terms arising from the static dipole moment and the dipole self-energy are essential for a correct description of the light-matter interaction in polaritonic chemistry. On the basis of a full quantum description, we simulate the excited-state dynamics and spectroscopy of MgH+ molecules resonantly coupled to an optical cavity.
