Detecting the presence of an irregularity/regularity or chaos in the ion flows of an evolving plant cell is an important task that can be unraveled by performing the analyses by different metrics. Here I show that the results of the advanced fluctuation estimation methods that are obtained from the time series that is generated by the extracellular ion fluxes of tobacco pollen tubes (Nicotiana tabacum L.) have long-range correlations at critical temperatures. Further experimental evidence has been found to support the claim that the autonomous growth organization of extreme plant cell expansion is accomplished by self-organizing criticality (SOC), which is an orchestrated instability that occurs in an optimally evolving cell. The temperature-induced synchronous action of the ionic fluxes that are manifested, inter alia, by minimal dynamic entropy enabled the molecularly encoded information about germination and optimal growth temperatures of tobacco pollen tubes to be determined.Understanding the mechanisms behind memory, learning, and behavior is crucial to human development and significant research has been done in this area. Classical and operant conditioning and other theories of learning have elucidated different mechanisms of learning and how it modulates behavior. Even with advances in this area, questions remain on how to unlearn faulty ideas or extinguish maladaptive behaviors. In this paper, a novel theory to improve our understanding of this area is proposed. The theory proposes that as a consequence of the brain's energy efficiency evolutionary adaptations, all learning following memory consolidation, reconsolidation, and repeated reinforcements or strengthening over time, results in a phenomenon called mental representation block. The implications of this block on learning and behavior are significant and broad and include cognitive biases, belief in a creator or God, close-mindedness, dogmatism, physician misdiagnosis, racism, homophobia, and transphobia, susceptibility to deception and indoctrination, hate and love, artificial intelligence and creativity.Insectivorous bats capture their prey in flight with impressive success. They rely on the echoes of their own ultrasonic vocalization that yield acoustic snapshots, which enable target tracking on a rapid time scale. This task requires the use of intermittent information to navigate a dynamically changing environment. Bats may solve this challenging task by building internal models that estimate target velocity to anticipate the future location of a prey item. This has been recently tested empirically in perched bats tracking a target moving across their acoustic field. In this report, we build on past work to propose a new model that describes bat flight trajectories employing predictive strategies. Furthermore, we compare this model with a previous model of bat target interception that has also been employed by some visually guided animals parallel navigation.

It is rare to see heart block as the first-and-only presentation of infectious myocarditis. We report the case of a young healthy patient who presented with syncope secondary to a complete heart block. It was caused by acute presumed viral myocarditis. The diagnosis was confirmed with cardiac magnetic resonance imaging. With close monitoring, the EKG abnormalities resolved over the following 5 days. In this case report, we present the importance of several imaging tools to diagnose a rare and reversible cause of conduction disturbances. In at-risk individuals, clinicians should rule out a treatable cause of heart block before proceeding with permanent pacemaker implantation due to enormous clinical and cost implications involved.Tuberculosis is an endemic disease in Senegal. It rarely affects the skin. In these patients it is characterized by clinical polymorphism. It accounts for 2% of extra-pulmonary tuberculosis. We here report the case of an immunocompetent patient with tuberculosis affecting the buttock characterized by lesions gummy in consistency revealing active pulmonary involvement. This study involved a 47-year-old man admitted for a painful swelling in the right gluteal region that had evolved for four years. Physical examination objectified a polyfistulized hardened plaque characterized by confluent nodules and discharge of yellowish pus in the lower and inner face of the right buttock associated with bilateral inguinal inflammatory adenopathies. The diagnosis of skin tuberculosis was retained based on histological examination which showed tuberculoid granuloma and the detection of Alcohol-Acid Resistant Bacilli (BAAR) in the gastric fluid. Thoracoabdominopelvic CT scan showed multiple bilateral basal lung micronodules with a "bud tree" appearance. Orludodstat in vivo Serologic testing for HIV and HBV were negative. The patient achieved recovery after six months of tuberculosis treatment. In endemic areas, skin tuberculosis is characterized by clinical polymorphism. It should be suspected in patients with perineal abscess lesion.

as COVID-19 pandemic is rapidly evolving, there is a whole reorganization in hospitals to concentrate more resources to face the crisis. The purpose of this study is to evaluate the impact of COVID-19 disease on urological activity in Tunisia. To assess the differences in the management of urological conditions between the private and the public field.

a survey was addressed to all certified urologists working in Tunisia in both the public and private sectors (n=194) using the national database of active urologists available and updated. We either called them or looked them up through email or social media. The form was open from March the 28

to April the 3

. Results were obtained via spreadsheet and analysed using SPSS 23.0.

one hundred and twenty urologists have filled in the form. Consultations at the outpatient office were restricted to urgent cases in 66% (n=79). Telemedicine was more used by urologists in private than in public fields p=0.03. Urologists in private sector followed more the sterilization protocol of the hospital/clinic and used more disposable materials whenever possible p=0.
