Mechanisms creating homogamy in depressiveness in couples: A longitudinal study from Czechia
Abstract Couples often resemble each other in characteristics like depression, but the reasons for this homogamy (i.e., similarity) remain unclear. We investigated two potential mechanisms: preference for a self-similar partner and convergence (i.e., increasing similarity) over time. In a nationally representative sample of 2,793 Czech individuals who we surveyed three times in one year, we examined self-reports of participants’, their ideal partners’, and their actual partners’ “pessimism and depressiveness”. Participants preferred partners less depressive than themselves, yet their actual partners were more depressive than desired. Those who ended their relationships showed a greater ideal-versus-actual partner discrepancy than those who stayed together. In stable relationships, individuals adjusted their ideal preferences to align more closely with their actual partners over time. We identified four relationship classes with latent class growth modeling based on self and partner evaluations: both non-depressive, both depressive, self depressive and partner non-depressive, and self non-depressive and partner depressive. Romantic relationships were most stable when both partners were non-depressive and most likely to dissolve when both were depressive. While we failed to detect convergence overall, we found it within heterogamous (i.e., dissimilar) classes. Overall, our findings suggest that homogamy and heterogamy in depressiveness are complexly associated with relationship maintenance.
The protective and chemotherapeutical role of amygdalin in induced mammary cancer in experimental mice and upregulation of related genes
Abstract Breast cancer is a prominent health issue among oncological diseases in emerging nations. The study sought to assess the significant function of amygdalin as a protective and chemotherapeutical substance in combating this lethal condition, either independently or in conjunction with tamoxifen therapy. Breast cancer in mice was induced by 7,12-Dimethylbenz(a)anthracene (DMBA). Mice were divided into six groups, 15 mice in each group. (i) control group, (ii) carcinogenic group, (iii) tamoxifen-treated group, (iv) Amygdalin-treated group, (v) (Amygdalin + tamoxifen) group, (vi) Amygdalin protective group. Results revealed that DMBA-induced breast cancer caused a significant increase in biochemical parameters such as CEA, CA15.3, CA125, PRL, E2, urea, creatinine, ALT, AST, and ALP and a substantial increase in gene expression of TNF-α and BcL-2. In contrast, amygdalin administrations alone or in co-administration with tamoxifen could ameliorate breast cancer by declining TNF-α, BcL-2 and attenuating the biochemical parameters. Amygdalin administrations showed a significant increase in SOD and GPx antioxidants and upregulation of Caspase-3 and P53 in breast tissue. Moreover, flow cytometric analysis revealed that amygdalin administrations were correlated with CD20 and CD44 and promoted the cell cycle and apoptosis in carcinogenic mice. Indeed, the above results were confirmed by the histopathological examinations, which showed that the DMBA group had proliferated microductular carcinoma with marked mononuclear inflammatory cell infiltration, which decreased by the Amygdalin administrations. In conclusion, amygdalin administration may be effective in preventing breast cancer and exhibiting chemotherapeutic properties.
Placebo treatment entails resource-dependent downregulation of negative inputs
Abstract Clinical trials with antidepressants reveal significant improvements in placebo groups, with effects of up to 80% compared to real treatment. While it has been suggested that treatment expectations rely on cognitive control, direct evidence for affective placebo effects is sparse. Here, we investigated how cognitive resources at both the behavioral and neural levels influence the effects of positive expectations on emotional processing. Forty-nine healthy volunteers participated in a cross-over fMRI study where positive expectations were induced through an alleged oxytocin nasal spray and verbal instruction. Participants completed a spatial cueing task that manipulated attention to emotional face distractors while being scanned and were characterized regarding their general attention control ability. Placebo treatment improved mood and reduced distractibility from fearful compared to happy faces, particularly when more attentional resources were available for processing face distractors. This aligned with changes in activation and functional coupling within prefrontal-limbic networks, suggesting that expectations induce top-down regulation of aversive inputs. Additionally, neurobehavioral effects correlated with individual control ability. Our findings highlight the critical role of cognitive resources in verbally instructed placebo effects. This may be particularly relevant in patients with major depressive disorder, who often demonstrate enhanced negativity processing but have limited cognitive control capacity.

Optimally scrambling chiral spin-chain with effective black hole geometry
Abstract There is currently significant interest in emulating the essential characteristics of black holes, such as their Hawking radiation or their optimal scrambling behavior, using condensed matter models. In this article, we investigate a chiral spin-chain, whose mean field theory effectively captures the behavior of Dirac fermions in the curved spacetime geometry of a black hole. We find that within the region of the chain that describe the interior of the black hole, strong correlations prevail giving rise to many-body chaotic dynamics. Employing out-of-time-order correlations as a diagnostic tool, we numerically compute the associated Lyapunov exponent. Intriguingly, we observe a linear increase in the Lyapunov exponent with temperature within the black hole’s interior at low temperatures, indicative of optimal scrambling behavior. This contrasts with the quadratic temperature dependence exhibited by the spin-chain on the region outside the black hole. Our findings contribute to a deeper understanding of the interplay between black hole geometry and quantum chaos, offering insights into fundamental aspects of quantum gravity.

Longitudinal association of SGLT2 inhibitors and GLP-1RAs on falls in persons with type 2 diabetes
Abstract Low lean body mass increases fall risk. Some diabetes medications, specifically SGLT2 inhibitors and GLP-1RAs, can cause muscle and body mass loss. This study assessed their association on falls in type 2 diabetes patients. An annual fall survey was conducted for up to 5 years on individuals with type 2 diabetes admitted to our department. Fall risk factors were identified using discrete-time survival analysis. The study observed 471 participants over a median period of 2 years. The participants had a median age of 64 years, with a fall incidence rate of 17.1 per 100 person-years. Independent fall predictors identified were fall history, SGLT2 inhibitor use, and age. The odds ratios (95% confidence intervals) for using SGLT2 inhibitors only, GLP-1RAs only, and both combined were 1.80 (1.10–2.92), 1.61 (0.88–2.84), and 2.89 (1.27–6.56), respectively. SGLT2 inhibitor use was an independent risk factor for falls, while GLP-1RAs’ effects were not statistically significant. However, the combined use of SGLT2 inhibitors and GLP-1RAs significantly increased the risk of falls. Therefore, it is important to consider this risk when prescribing these medications to people with type 2 diabetes.
