Projectile technology is considered to appear early in the southern African Middle Stone Age (MSA) and the rich and high resolution MSA sequence of Sibudu Cave in KwaZulu-Natal has provided many new insights about the use and hafting of various projectile forms. We present the results of a functional and technological analysis on a series of unpublished serrated bifacial points recently recovered from the basal deposits of Sibudu Cave. These serrated tools, which only find equivalents in the neighbouring site of Umhlatuzana, precede the Still Bay techno-complex and are older than 77 ka BP...

We describe colour, hardness, grain size, geological type and surface modifications of ochre pieces excavated, first by Malan and later by Harper, from the Middle Stone Age (MSA) of Rose Cottage Cave, 96, 000 to 30, 000 years ago. Soft, bright-red shales are abundant, and most ochre has clayey or silty grain sizes. The post-Howiesons Poort layers contain the most ochre pieces, but the Howiesons Poort layers have the highest frequency of ochre per sediment volume. The pre-Howiesons Poort layers have the highest utilization rate...

For decades, one of the overarching objectives of self-assembly science has been to define the rules necessary to build functional, artificial materials with rich and adaptive phase behavior from the bottom-up. To this end, the computational and experimental efforts of chemists, physicists, materials scientists, and biologists alike have built a body of knowledge that spans both disciplines and length scales. Indeed, today control of self-assembly is extending even to supramolecular and molecular levels, where crystal engineering and design of porous materials are becoming exciting areas of exploration...

The Really Interesting New Gene (RING)-type E3 ligase, Keep on Going (KEG) plays a critical role in Arabidopsis growth after germination and the connections between KEG and hormone signaling pathways are expanding. With regards to abscisic acid (ABA) signaling, KEG targets ABA-responsive transcription factors abscisic acid insensitive 5, ABF1 and ABF3 for ubiquitination and subsequent degradation through the 26S proteasome. Regulation of E3 ligases through self-ubiquitination is common to RING-type E3 ligases and ABA promotes KEG self-ubiquitination and degradation...

Marker-assisted selection (MAS) in stone fruit (Prunus species) breeding is currently difficult to achieve due to the polygenic nature of the most relevant agronomic traits linked to fruit quality. Genotyping by sequencing (GBS), however, provides a large quantity of useful data suitable for fine mapping using Single Nucleotide Polymorphisms (SNPs) from a reference genome. In this study, GBS was used to genotype 272 seedlings of three F1 Japanese plum (Prunus salicina Lindl) progenies derived from crossing "98-99" (as a common female parent) with "Angeleno," "September King," and "September Queen" as male parents...

Hyperoxaluria is a stress that leads to calcium oxalate crystal deposition which further causes inflammation and renal cell necroptosis. Many studies have linked osteopontin expression with apoptosis and inflammation but so far its association with apoptosis with regard to hyperoxaluria is undiscovered. Moreover, a recent report has suggested that osteopontin induces endoplasmic reticulum stress and subsequently apoptosis in myocytes. In this study, the impact of hyperoxaluria on the modulation of osteopontin expression and endoplasmic reticulum (ER) stress mediated apoptosis in rats is explored...

OBJECTIVES: Preeclampsia is characterised by systemic endothelial cell dysfunction thought to be triggered by toxic/dangerous factors from the placenta, including placental extracellular vesicles (EVs). Why placental EVs become toxic is unknown. We previously reported that preeclamptic sera produced toxic/dangerous placental macrovesicles but whether small EVs are also toxic/dangerous in preeclampsia is unknown. STUDY DESIGN: First trimester placental explants were treated with 10% preeclamptic or control sera (n=10) for 24h...

OBJECTIVES: The prevalence of urolithiasis is increasing worldwide. Diabetes mellitus (DM) is characterized by insulin resistance, which increases the risk of kidney stone formation. Adiponectin is an insulin-sensitizing and anti-inflammatory cytokine, which is known to improve glucose tolerance and insulin resistance in humans. The association of insulin and adiponectin with kidney stones is not clear. Hence, the present study aim to assess the serum levels of adiponectin and insulin resistance in DM patients with urolithiasis in comparison to those without...

Many enzymes, such as laccases, are involved in the saprotrophic lifestyle of fungi and the effects of those may be linked to enhanced bioweathering on stone surfaces. To test this hypothesis, we studied the decomposition of kerogen-enriched lithologies, especially with black slate containing up to 20% of Corg. Indeed, a formation of ditches with attached hyphal material could be observed. To address enzymes involved, proteomics was performed and one group of enzymes, the multicopper oxidase family members of laccases, was specifically investigated...

INTRODUCTION: Interventional radiologist may be hesitant to obtain upper pole access for percutaneous nephrolithotomy (PCNL) due to a higher complication rate. Renal access gained by urologists may achieve higher stone-free rates with similar complication rates. We evaluate our institution's contemporary results of percutaneous renal access in the upper pole for nephrolithotomy by urologists, which we believe both safe and efficacious. MATERIALS AND METHODS: This retrospective chart review included all PCNL's performed by fellowship-trained endourologists from 2003 to 2014 at a single institution...
