The fauna from Mughr el-Hamamah, Jordan: Insights on human hunting behavior during the Early Upper Paleolithic.

As a corridor for population movement out of Africa, the southern Levant is a natural laboratory for research exploring the dynamics of the Middle-to-Upper Paleolithic transition. Yet, the number of well-preserved sites dating to the initial millennia of the Early Upper Paleolithic (EUP; ∼45-30 ka) remains limited, restricting the resolution at which we can study the biocultural and techno-typological changes evidenced across the transition. With EUP deposits dating to 45-39 ka cal BP, Mughr el-Hamamah, Jordan, offers a key opportunity to expand our understanding of EUP lifeways in the southern Levant.

Soil organic carbon, aggregation and fungi community after 44 years of no-till and cropping systems in the Central Great Plains, USA.

Implementing sustainable agricultural land management practices such as no-till (NT) and diversified crops are important for maintaining soil health properties. This study focuses on the soil health of three long-term (44 years) tillage systems, NT, reduced tillage (RT), and conventional tillage (CT), in monoculture winter wheat-fallow (W-F) (Triticum aestivum L.) and wheat-soybean (W-S) (Glycine max (L.

Extended longevity of DNA preservation in Levantine Paleolithic sediments, Sefunim Cave, Israel.

Paleogenomic research can elucidate the evolutionary history of human and faunal populations. Although the Levant is a key land-bridge between Africa and Eurasia, thus far, relatively little ancient DNA data has been generated from this region, since DNA degrades faster in warm climates. As sediments can be a source of ancient DNA, we analyzed 33 sediment samples from different sedimentological contexts in the Paleolithic layers of Sefunim Cave (Israel).

Managing Postoperative Nausea With an Application of Ice Pack to the Posterior Upper Neck.

Purpose: Measure effectiveness of a non-pharmacological approach to manage postoperative nausea (PON) by applying an ice pack to the posterior upper neck.

Design: This was an observational quality improvement project. The sample included adults 18 years old and older who received general anesthesia (inhalation and/or intravenous), recovering in Phase I or Phase II postoperative care unit (PACU) experiencing very mild to moderate nausea.

Provider behaviors that predict motivational statements in adolescents and young adults with HIV: a study of clinical communication using the Motivational Interviewing framework.

Medical care providers' use of Motivational Interviewing (MI) is linked to improved medication adherence, viral load, and associated behaviors in adolescents and young adults living with HIV. Mastering MI is difficult for busy providers; however, tailoring MI training to the specific MI communication strategies most relevant for HIV treatment context may be a strategy to increase proficiency. The present study aimed to identify communication strategies likely to elicit motivational statements among adolescent-young adult patients living with HIV.

Self-Selected Motivational Music on the Performance and Perceived Exertion of Runners.

Clark, JC, Baghurst, T, and Redus, BS. Self-selected motivational music on the performance and perceived exertion of runners. J Strength Cond Res 35(6): 1656-1661, 2021-Music is used by athletes and exercisers to improve performance outcomes, but it is less known whether its properties can enhance performance at maximal intensity.

Lateral Knee Compartment Portals: A Cadaveric Study Defining a Posterolateral Viewing Safety Zone.

Purpose: This study attempted to define a reproducible "safe zone" based on extra- and intra-articular knee anatomy for placing one or 2 accessory portals in the lateral tibiofemoral compartment for posterolateral region viewing.

Methods: Standard portals were created in 10 cadaveric knees to enable posterolateral region arthroscopic lateral tibiofemoral joint compartment viewing. After identifying the lateral knee surface tissue "soft spot," an accessory posterolateral portal (A) was created using an 18-gauge spinal needle and 4-mm cannula under direct visualization of a 70° arthroscope through the anteromedial portal.

The Howieson's Poort fauna from Sibudu Cave: Documenting continuity and change within Middle Stone Age industries.

The Howieson's Poort (HP; ∼65-59 ka) continues to be a source of interest to scholars studying human behavioral evolution during the Late Pleistocene. This is in large part because the HP preserves evidence for a suite of innovative technologies and behaviors (including geometric backed tools and engraved ostrich eggshell), but also because the disappearance of the innovative behaviors associated with this phase is not well understood. Here, I present taphonomic and taxonomic data on the full sample of macromammal remains excavated from the HP deposits at Sibudu Cave under the direction of Lyn Wadley.

Early Upper Paleolithic chronology in the Levant: new ABOx-SC accelerator mass spectrometry results from the Mughr el-Hamamah Site, Jordan.

Methodological developments and new paleoanthropological data remain jointly central to clarifying the timing and systemic interrelationships between the Middle-Upper Paleolithic (MP-UP) archaeological transition and the broadly contemporaneous anatomically modern human-archaic biological turnover. In the recently discovered cave site of Mughr el-Hamamah, Jordan, in situ flint artifacts comprise a diagnostic early Upper Paleolithic (EUP) assemblage. Unusually well-preserved charcoal from hearths and other anthropogenic features associated with the lithic material were subjected to acid-base-wet oxidation-stepped combustion (ABOx-SC) pretreatment.

Scientific basis for the selection of vascular closure techniques.

If this educational program heightens the surgeon's, resident's, and student's interest in the biology of vascular wound closure and infection, the long years occupied in our search for improved methods of wound management would more than fulfill our expectations. As with any master surgeon, he/she must understand the tools of his/her profession. This linkage between a surgeon and surgical equipment is a closed kinematic chain in which the surgeon's power is converted into finely coordinated movements that result in vascular wound closure with the least possible scar and without infection.

Scientific basis for the selection of skin closure techniques.

This scientific article was designed to teach the individual reader the scientific basis for suture and needle selection as well as to illustrate the appropriate surgical techniques involved in wound repair of skin incisions. Because the US Food and Drug Administration permits 1.5% of the sterile surgical gloves to have holes, the operating room personnel should wear sterile surgical double-glove hole indication systems that detect holes in the outer glove.

Wound closure sutures and needles: a new perspective.

Ideally, the choice of the suture material should be based on the biological interaction of the materials employed, the tissue configuration, and the biomechanical properties of the wound. Measurements of the in vivo degradation of sutures separate them into two general classes: absorbable and nonabsorbable sutures. The nonabsorbable sutures and absorbable sutures are classified according to their origin.

Scientific basis for the selection of surgical staples and tissue adhesives for closure of skin wounds.

During the last four decades, there have been revolutionary advances in the development of skin staples as well as tissue adhesives. One of the purposes of this collective review is to provide an overview of recent advances in the development of metal and absorbable skin staples and tissue adhesives. In addition, we will provide technical considerations in the use of metal and absorbable skin staples and tissue adhesives during surgery.

Reducing accidental injuries during surgery.

All surgical healthcare professionals and their patients should be aware of exposure to blood from individuals infected with potentially transmissible disease. The site that was most susceptible to sharp injuries was the index finger of the surgeon's hand. It is also important to note that needles cause the vast majority of sharp injuries.

Postexposure prophylaxis for deadly bloodborne viral infections.

The purpose of this report is to discuss management of operating room personnel who have had occupational exposure to blood and other body fluids that might contain hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), and human T-cell lymphotropic virus type I (HTLV-I). HBV postexposure prophylaxis includes starting hepatitis B vaccine series in any susceptible unvaccinated operating room personnel who sustain an exposure to blood or body fluid during surgery. Postexposure prophylaxis with hepatitis B immune globulin (HBIG) is an important consideration after determining the hepatitis B antigen status of the patient.

Scales for assessing nonmotor symptom severity changes in Parkinson's disease patients with symptom fluctuations.

Unlabelled: ABSTRACT Background: In Parkinson's disease (PD), the impact of nonmotor symptoms can outweigh the effect of worsening physical mobility on Health-Related Quality of Life (HRQoL). As PD progresses, patients may experience more severe changes in fluctuating nonmotor symptoms.

Objective: This review summarizes nonmotor symptom assessments in patients with fluctuating symptoms, focusing on scales utilizing a daily-diary format for a broad spectrum of nonmotor symptoms.

Men's attitudes toward breastfeeding: findings from the 2007 Texas Behavioral Risk Factor Surveillance System.

Past research on breastfeeding demonstrates that male partners' support is a significant factor in mothers' decisions to breastfeed. This study explored the diversity of men's opinions about breastfeeding, for the purpose of increasing breastfeeding support among men. This study used the Texas sample of the 2007 Behavioral Risk Factor Surveillance System (BRFSS) to examine whether men's attitudes toward breastfeeding varied by their demographic characteristics and whether fathers' breastfeeding attitudes were related to couples' choice of infant feeding method.

Continuing education mitigates the negative consequences of adolescent childbearing.

Beginning childbearing during adolescence is consistently linked with negative outcomes for both children and parents. Many have attributed this association to maternal background characteristics which are often difficult to change through policy. Though maternal educational attainment is often a side effect of adolescent childbearing, it also represents a potential avenue through which we can help young mothers overcome the obstacles associated with an early birth.

Prevalence and risk factors for adult paternity among adolescent females ages 14 through 16 years.

To investigate sociodemographic factors associated with adolescent females ages 14-16 years having children fathered by males age 20 years or older and identify differences in correlates across rural, urban, and border areas. The method section was a cross-sectional study using Texas birth record data. From 2000 through 2004, there were 29,186 births to adolescent females aged 14-16 years with valid paternal age.

Multidimensional evaluation of managed relocation.

Managed relocation (MR) has rapidly emerged as a potential intervention strategy in the toolbox of biodiversity management under climate change. Previous authors have suggested that MR (also referred to as assisted colonization, assisted migration, or assisted translocation) could be a last-alternative option after interrogating a linear decision tree. We argue that numerous interacting and value-laden considerations demand a more inclusive strategy for evaluating MR.

Animal exploitation strategies during the South African Middle Stone Age: Howiesons Poort and post-Howiesons Poort fauna from Sibudu Cave.

As one of the few sites that preserve fauna from the Howiesons Poort (HP) and the immediately post-HP Middle Stone Age (MSA), Sibudu Cave provides a unique opportunity to explore the range of variability in subsistence behaviors during this important phase in human behavioral evolution. In addition to providing information on subsistence, the faunal assemblage serves as a means of reconstructing the environmental conditions during these two periods. While the HP fauna is dominated by species that prefer closed (particularly forested) habitats, the fauna from the upper-most layers of the post-HP MSA are largely representative of open conditions.
