The field of firearms and toolmark analysis has encountered deep scrutiny of late, stemming from a handful of voices, primarily in the law and statistical communities. While strong scrutiny is a healthy and necessary part of any scientific endeavor, much of the current criticism leveled at firearm and toolmark analysis is, at best, misinformed and, at worst, punditry. One of the most persistent criticisms stems from the view that as the field lacks quantified random match probability data (or at least a firm statistical model) with which to calculate the probability of a false match, all expert testimony concerning firearm and toolmark identification or source attribution is unreliable and should be ruled inadmissible...

We present a rare case of 32year old female with congenital diaphragmatic eventeration female presenting in an adult. She had symptoms of intermittent dyspnea and occasional epigastric discomfort. Patient had no previous history of trauma. Physical examination showed bowel sound involving the left hemithorax. Imaging modalities confirmed the diagnosis of a congenital left diaphragmatic eventeration. Patient underwent plication of the diaphragm using the abdominal approach. Intra-operatively, the left diaphragm was attenuated...

Given that autobiographical memory provides a cognitive foundation for the self, we investigated the relative importance of visual, auditory and olfactory autobiographical memories for the self. Thirty subjects, with a mean age of 35.4years, participated in a study involving a three×three within-subject design containing nine different types of autobiographical memory cues: pictures, sounds and odors presented with neutral, positive and negative valences. It was shown that visual compared to auditory and olfactory autobiographical memories involved higher cognitive and emotional constituents for the self...

Comparative research on aphasia and aphasia rehabilitation is challenged by the lack of comparable assessment tools across different languages. In English, a large array of tools is available, while in most other languages, the selection is more limited. Importantly, assessment tools are often simple translations and do not take into consideration specific linguistic and psycholinguistic parameters of the target languages. As a first step in meeting the needs for comparable assessment tools, the Comprehensive Aphasia Test is currently being adapted into a number of languages spoken in Europe...

Cellulose synthesis in bacteria is a complex process involving the concerted action of several enzymes whose genes are often organized in operons. This process influences many fundamental physiological aspects such as bacteria and host interaction, biofilm formation, among others. Although it might sound contradictory, the participation of cellulose-degrading enzymes is critical to this process. The presence of endoglucanases from family 8 of glycosyl hydrolases (GH8) in bacterial cellulose synthase (Bcs) complex has been described in different bacteria, including the model organism Komagataeibacter xylinus; however, their role in this process is not completely understood...

Covariations of acoustic features provide redundancy in rapidly changing soundscapes: Hearing one feature enables a listener to infer another if these 2 features normally covary. However, it is unknown whether situational demands affect the degree to which covariations influence perceptual inferences. We exploited a perceptual interdependency between modulation rate and frequency and examined, in 6 experiments, whether challenging situations would alter the degree to which people rely on frequency information to make decisions about modulation rate...

OBJECTIVE: One in 4 women and 1 in 10 men in the United States are survivors of sexual abuse (SA). For these survivors, healthcare experiences may trigger memories, thoughts, feelings or sensations related to this past abuse. Such triggering can be associated with negative responses to healthcare (e.g., anxiety, avoidance). However, to date, no healthcare triggering assessment tool exists. Therefore, the study goal was to describe the prevalence of healthcare triggering, to develop a brief Healthcare Triggering Questionnaire (HTQ), and to examine its initial validity...

Clinical trials and research studies are being conducted worldwide at a rampant pace leading to generation of large amount of data. However, to reap the benefits of the data generated it is important that this data is shared with the general public without which it can be deemed useless. Despite its importance being known to us, data sharing does not come without its share of problems and it is not as easy to execute as it sounds on-paper. Over the past few years, multiple coveted organizations around the world involved in research activities have come up with their respective guidelines and initiatives to make sure the sharing of research data is smooth and ethical...

We assessed how visually impaired (VI) people perceived their own auditory abilities using an established hearing questionnaire, the Speech, Spatial, and Qualities of Hearing Scale (SSQ), that was adapted to make it relevant and applicable to VI individuals by removing references to visual aspects while retaining the meaning of the original questions. The resulting questionnaire, the SSQvi, assessed perceived hearing ability in diverse situations including the ability to follow conversations with multiple speakers, assessing how far away a vehicle is, and the ability to perceptually segregate simultaneous sounds...

Music can be thought of as a dynamic path over time. In most cases, the rhythmic structure of this path, such as specific sequences of strong and weak beats or recurring patterns, allows us to predict what and particularly when sounds are going to happen. Without this ability we would not be able to entrain body movements to music, like we do when we dance. By combining EEG and behavioral measures, the current study provides evidence illustrating the importance of ongoing neural oscillations at beat-related frequencies-i...

A low activity variant of endoplasmic reticulum aminopeptidase 1 (ERAP1), Hap10, is associated with the autoinflammatory Behcet s disease (BD) in epistasis with HLA-B*51, which is the main risk factor for this disorder. The role of Hap10 in BD pathogenesis is unknown. We sought to define the effects of Hap10 on the HLA-B*51 peptidome and to distinguish these effects from those due to HLA-B*51 polymorphisms unrelated to disease. The peptidome of the BD-associated HLA-B*51:08 subtype expressed in a Hap10-positive cell line was isolated, characterized by mass spectrometry, and compared with the HLA-B*51:01 peptidome from cells expressing more active ERAP1 allotypes...

Most models of auditory cortical (AC) population coding have focused on primary auditory cortex (A1). Thus, our understanding of how neural coding for sounds progresses along the cortical hierarchy remains obscure. To illuminate this, we recorded from AC fields, A1 and middle-lateral belt (ML) of rhesus macaques. We presented amplitude-modulated (AM) noise during both passive listening and while the animals performed an AM detection task ("Active" condition). In both fields, neurons exhibit monotonic AM-depth tuning, with A1 neurons mostly exhibiting increasing rate-depth functions and ML neurons ~evenly distributed between increasing and decreasing functions...

The rat inferior colliculus (IC) is a major midbrain relay for ascending inputs from the auditory brainstem and has been suggested to play a key role in the processing of aversive sounds. Previous studies have demonstrated that auditory fear conditioning (AFC) potentiates transient responses to brief tones in the IC, but it remains unexplored whether AFC modifies responses to sustained periodic acoustic stimulation - a type of response called steady-state evoked potential (SSEP). Here we used an amplitude-modulated tone - 10 kHz tone with a sinusoidal amplitude modulation of 53...

A fundamental adaptive mechanism of auditory function is inhibitory gating (IG), which refers to the attenuation of neural responses to repeated sound stimuli. IG is drastically impaired in individuals with emotional and cognitive impairments (i.e., posttraumatic stress disorder). The objective of this study was to test whether chronic stress impairs the IG of the auditory cortex (AC). We used the standard two-tone stimulus paradigm and examined the parametric qualities of IG in the AC of rats by recording the electrophysiological signals of a single-unit and local field potential (LFP) simultaneously...

BACKGROUND: The use of acellular dermal matrix (ADM) has become the standard of care in breast reconstruction. However, the majority of current studies are biased or combine large databases introducing inherent flaws. Here, we present a prospective single surgeon experience comparing three ADM. METHODS: All expander based breast reconstructions between 2014 and 2015 using ADM were included. RESULTS: Eighteen patients (32 breasts) underwent reconstruction using Flex Pliable, 15 patients (22 breasts) used Alloderm, and 14 patients (20 breasts) had Dermacell...

The mitigation potential of avenue tree species needs a sound understanding, especially for landscape planning or planting tree species on roadside, especially in city limits where there is huge traffic due to more number of vehicles. A preliminary study was conducted to investigate the impact of heavy traffic movement and pollution thereof on physiological functioning of Lagerstroemia speciosa trees planted on roadside in terms of carbon absorption, mitigation potential and adaptive behavior. Trees on roadside exhibited reduced carbon assimilation (36...
