This article discusses the case of a 69-year-old woman who was referred for a colonoscopy after a positive fecal occult blood test. During the colonoscopy, a protruding lesion was found at the appendiceal orifice. Biopsies confirmed normal mucosa, but a CT scan showed mild appendiceal thickening. During surgery, an appendiceal intussusception was identified, and a limited stapled caecectomy was performed. The histology confirmed a grade-one neuroendocrine tumor in the distal appendix. The article emphasizes the importance of awareness of appendiceal intussusception and recommends limited resection to facilitate pathological assessment before considering formal resection.

An excavation carried out on the southern side of the six-chambered inner gatehouse at Lakhish exposed the gate passage, four piers and three chambers. The eastern chamber comprised two rooms, with a cultic niche in one of the room's back wall and an altar in front of it. The chamber probably served as a gate shrine, and was desecrated during Hezekiah's cult reform, when a toilet seat was placed next to the altar and the altar horns were trimmed. Evidence of Sennacherib's destruction in 701 BCE was manifest by the presence of arrowheads, slingstones and collapsed burned mud bricks. The pottery assemblage aligns with previous finds from Lakhish Level III, with all vessel forms known from Iron IIB strata in Judah. [ABSTRACT FROM AUTHOR]

This paper presents the results of a morphometric analysis conducted on the arrowheads from the battlefield of Las Navas de Tolosa (1212), a battle between the Almohads troops and the Iberian Christian kingdoms. It took place near Santa Elena (Jaén), in the southern Iberian Peninsula. Our objective is to bring new data on the operational chains of these iron artefacts at the beginning of the thirteenth century. The results allow us to delve into the specialisation of blacksmiths, to approach production techniques, and to quantify the process of standardisation according to the measurement systems within medieval Christian and Andalusian societies. In short, this research addresses new and relevant approaches to the field of weaponry and medieval metallurgy, transcending traditional typologies. [ABSTRACT FROM AUTHOR]

The storage period of arrowhead vegetable is short and their applications in food processing are severely limited. To extend the shelf-life of arrowheads, this study innovatively combined electrostatic field (EF) and emulsion coating for the preservation of arrowheads. The O/W Pickering emulsion prepared by chitosan-tea polyphenol mixture/conjugate (PE-M/PE-C) were characterized by particle size distribution, zeta potential, and micromorphology. After treating by EF and emulsion coating, arrowheads were stored 4 °C for 20 days. The physicochemical properties of arrowheads during storage were measured. Results showed that PE-M had a smaller particle size (505.40 nm) and higher stability than PE-C (658.50 nm). However, PE-C had better performances than PE-M in inhibiting weight loss and respiratory rate, as well as maintaining the hardness. The utilization of EF significantly decreased peroxidase activities in arrowheads and inhibited browning. Compared with the control group, other groups treated by electrostatic field and emulsion coating showed better preservation effects on arrowheads, particularly the EF + MC group, which extended their shelf-life more than 10 days. This study provides an effective method for extending the shelf-life of arrowheads compared with traditional low-temperature preservation, and it also gives a new strategy for more fresh food preservation in the future. [Display omitted] • Grafted polyphenol lowers emulsion stability by enhancing chitosan's hydrophilia. • Electric field has stronger peroxidase activity inhibition than edible coating. • Water conversion in arrowhead vegetables causes textural softness and weight loss. • Electric field combined with coating extends shelf-life >10 days at 4 °C storage.

Abstract. This study concerns 580 bronze arrowheads from five burials of the Kichigino I cemetery (southern Trans-Urals), dated from the second half of the sixth to the second half of the fourth centuries BC. The main component in all arrowheads was copper with admixtures of arsenic, antimony, lead, tin and nickel. The research revealed that the Early nomads’ non-ferrous metal sources changed approximately in the middle of the fourth century BC. Initially, almost all metal came from Itkul metallurgy and metalworking center located in the southern Trans-Urals forest-steppe area. Pure copper without addition as well as alloys with additive of arsenic, occasionally with arsenic and antimony were overwhelmingly applied. In the next period, there are plenty of arrowheads made of copper alloys containing lead as a component; its sources are located to the southwest and west of the Trans-Urals. The transition to new metal sources was caused on the one hand by massive migrations of the Trans-Ural steppe nomadic population to the southern Cis-Urals, on the other, by gradual decline of the Itkul center of metallurgy during the fourth century BC and by the complete reserve depletion in the third century BC. Reuse of tin-alloyed bronze items from earlier times was caused by lack of the non-ferrous metal supplied by the Itkul metallurgists. Furthermore, results of metals analysis indicate that there is no relationship between the shape of the arrowheads and the composition of the metal in them. Arrowheads of the same shape could be made of different metal composition, and, by contrast, arrowheads of different shapes were made from the same metal.

The paper presents an overview of a unique Maeotian horse bridle assemblage from the cemetery of Starokorsunskaya settlement No. 2 located on the right bank of the Kuban river. The horse was buried lying with its abdomen in a ventral position, its legs folded up underneath its abdomen, its face turned east-north-east. The eastern part of the burial construction was damaged and collapsed into the storage reservoir. It is possible that the person‘s burial who was accompanied by the horse, also disintegrated. Two iron socketed arrowheads dating back to the 6th – 3rd centuries BC were found between the horse ribs. In the horse’s teeth there were two-piece iron bits with rigid check-devices; more than six sets of iron single-gnawed bits lay next to the horse. Two-piece iron bits were equipped with rigid check-devices in the form of short crosses, the ends of which were forged into blades with sharp small teeth (variant B). The check-devices of this variant were recorded in the Maeotian culture of the second quarter – middle 4th century BC, and possibly existed throughout the first half of the next century. However, the latest assemblages with such check-devices from the sites on the right bank of the Kuban river dating back precisely to the beginning – the first quarter of the 3rd century BC according to the amphorae containers. A group of single-gnawed bits consisted of six sets with cheek-pieces of different types. The bits themselves (except for one set) are pseudo-twisted, with a movable ring at one end and a cheek-piece at the other. Cheek-pieces with an 8-shaped widening in the middle are of two different types. Three pairs of bits are equipped with a pseudo-twisted rod-shaped cheek-pieces, the other three blade cheek-pieces with conical and moon-shaped pendants. Cheeks of these types do not yet have close analogies either in the Maeotian or in the Scythian culture, and the singlegnawed bits were never found anywhere before. According to cross-shaped rigid check-devices on two-piece bits, the chronology of the burial is limited to the second quarter of the 4th – beginning of the 3rd century BC. The set of single-gnawed bits was most likely intended for training young horses on the lane. The presence of six sets of such bits in the burial probably indicates that a horse-breaker was buried there

Materials of a single-layer site of the late Bronze Age Balakino I are published in the paper. The collection of the finds comprises 7883 items. Of these, 6398 are fragments of ceramics (about 300 vessels) and 1389 are stone products. The ceramic complex is represented by vessels of the Cherkaskul–Mezhovka (predominate) and Koptyaki types. Among the stone items, the most expressive ones are arrowheads, Balakino type scrapers and beaters. The arrowheads were treated with flat pressing retouching and made in the form of regular wide triangles with a flat or slightly concave base. The Balakino type of scrapers are widely known at the sites of the Late Bronze and Early Iron Ages. A special feature of the complex of stone products is the presence of 24 massive beaters, nine of which were found in the hoard. The presence of a large number of beaters at the site suggests its connection with the extraction and crushing of ore.

In this study, we firstly developed an antioxidant and pH-sensitive film based on arrowhead starch (AS), κ-carrageenan (KC) and black chokeberry extract (BCE) and its physical and structural properties were investigated. We found BCE showed different colors in different pH solutions and incorporation with KC and BCE could significantly decrease light transmittance, increase thickness, elongation at break and pH-sensitive property of AS film. The results of structural property assay indicated that there were some intermolecular interactions between BCE and AS/KC in AS-KC-BCE films. Secondly, we investigated the rheological property of AS, AS-KC and AS-KC-BCE suspensions and found the suspensions showed an obvious shear-thinning behavior with high apparent viscosity. Finally, the functional properties of AS-KC-BCE films were investigated and AS-KC-BCE films showed strong scavenging activity on DPPH free radical and presented visible colour changes in response to the changes of the chicken wing qualities. The results suggest that AS-KC-BCE films can be used in active and intelligent packaging of food industry. [ABSTRACT FROM AUTHOR]

The article presents recent discoveries made by the French Archaeological Mission to the Eastern Desert of Egypt in two Ptolemaic forts occupied in the second half of the 3rd century b.c., Bir Samut and Abbad, located along the road leading from Edfu to Berenike on the Red Sea Coast at the southern fringes of the Ptolemaic Empire. These artifacts, three copper-alloy arrowheads marked with the monogram BE and four Ptolemaic coins minted in Joppa, were recovered in contexts securely dated to the last decades of the 3rd century b.c. Due to the sealed stratigraphy and the discovery of thousands of ostraca and dozens of coins in the same deposits, it is clear that the forts and these objects were abandoned on the eve of the Great Theban Revolt in Egypt, around 207–206 b.c. These discoveries offer an occasion to reassess the corpus of similar arrowheads and coins found in the Eastern Mediterranean. The catalog presented here includes 45 BE arrowheads and 18 Joppa coins and a careful reassessment of the corpus suggests that they were probably produced by the Ptolemaic regime in direct association with the Fourth Syrian War, which ended with the Battle of Raphia in 217 b.c. The geographic distribution of the arrowheads and coins discussed in the article demonstrates the mobility of the Ptolemaic troops after this intense period of conflict. [ABSTRACT FROM AUTHOR]

Copper (Cu) is a heavy metal that pollutes the environment. One of the methods to resolve Cu pollutants is phytoremediation; which is the utilization of plants to absorb pollutants. Lanceleaf arrowhead (Sagittaria lancifolia) is proven to absorb copper. Metal absorption and translocation mechanism in plants have not been understood in more detail. This study aims to determine the ability of lanceleaf arrowhead (Sagittaria lancifolia) and the translocation factor in copper (Cu) phytoremediation. This study is an experimental study with a Completely Randomized Design (CRD). The experiment was conducted with eight treatments and three replications. The treatments were distinguished based on differences in the concentration of Cu used: 0 mg/L, 1 mg/L, 2 mg/L, and 3 mg/L. The concentration of Cu in the media and plant was measured for two weeks and four weeks, respectively. The results indicated that the value of the translocation factor at two weeks of exposure ranged from 0.57 to 0.6, while that at four weeks of exposure ranged from 1.5 to 2.33. Furthermore, at two weeks of exposure, the average metal loss ranged from 0.49 to 0.89 ppm, while that at four weeks of exposure ranged from 0.64 to 1.97 ppm. The highest effectiveness value of 66% was obtained in the three ppm treatment with four weeks of exposure. Meanwhile, the lowest effectiveness value of 30% was obtained in the three ppm treatment with two weeks of exposure. In addition, Sagittaria lancifolia was influential in the phytoremediation of copper (Cu) and could translocate metal into their tissues at four weeks of exposure. [ABSTRACT FROM AUTHOR]
