Abstract
BACKGROUND Plantar heel pain associated with plantar fascia pathology (PHP) is one of the most common running overuse injuries. Degeneration and changes in the mechanical properties of the plantar fascia associated with PHP can result in changes in foot kinematics during gait. RESEARCH QUESTION How do running gait foot kinematics differ between female and male runners with and without PHP? METHODS Retrospective study of 13 runners with PHP (7 female, 6 male) and a matched group of 13 uninjured runners (6 female, 7 male). A seven-segment foot model was used to quantify six functional articulations (rearfoot complex, lateral and medial midfoot, lateral and medial forefoot, and first metatarsophalangeal). Functional articulation ROM during early, mid, and propulsion running stance subphases was assessed. Two-way ANOVAs and Friedman's two-way ANOVA for ranks tests were conducted for normally distributed variables and non-normally distributed variables, respectively. RESULTS During early stance, PHP runners demonstrated significantly increased lateral midfoot eversion ROM compared to uninjured runners. During the propulsion phase, male runners with PHP demonstrated increased medial midfoot eversion and dorsiflexion ROM and increased medial forefoot plantar flexion compared to uninjured male runners. Also during propulsion, females with PHP went through significantly less medial forefoot plantar flexion ROM compared to uninjured female runners. SIGNIFICANCE Given the function of the plantar fascia to assist foot supination, the differences in runners with PHP, which were consistent with increased pronation or inadequate supination, may be the result of insufficient tension during the stance phase of running gait caused by degeneration of the plantar fascia. Further, the significant medial midfoot and medial forefoot group by sex interactions during propulsion suggest that PHP may affect male and female runners differently. Understanding the effect of PHP on foot function during running may aid in the development of future rehabilitation programs and/or treatment outcome assessments.

Abstract
OBJECTIVES This article describes the prevalence and epidemiological trends of COVID-19 mortality in the largest registry in the Kingdom of Saudi Arabia (KSA). STUDY DESIGN A prospective epidemiological cohort study using data from all healthcare facilities in KSA collected between March 23, 2020, and April 30, 2022. Data on the number of daily deaths directly related to COVID-19 were gathered, analyzed, and reported. METHOD Data analysis was carried out using national and regional crude case fatality rate and death per 100,000 population. Descriptive statistics using numbers and proportions were used to describe age, gender, nationality, and comorbidities. The mortality trend was plotted and compared with international figures. In addition, the most common comorbidities associated with mortality and the proportion of patients who received COVID-19 vaccine were reported. RESULTS The total reported number of deaths between March 23, 2020, and April 30, 2022, was 9085. Crude case fatality rate was 1.21%, and death per 100,000 population was 25.38, which compared favorably to figures reported by several developed countries. The highest percentages of deaths were among individuals aged between 60 and 69 years, males (71%), and individuals with diabetes (60%). Only 2.8% of mortalities occur in patients who received COVID-19 vaccine. Diabetes, hypertension, and heart failure had the highest attributable risk of mortality among patients who died due to COVID-19. CONCLUSION Case fatality rate and death per 100,000 population in KSA are among the lowest in the world due to multiple factors. Several comorbidities have been identified, namely, diabetes, hypertension, obesity, and cardiac arrhythmias.

Abstract
Acetylated corn starch was used as a fat replacer in beef patties and its effect on the physicochemical, textural, and sensory attributes of the patties was assessed during frozen storage (-20 °C) for 60 days. The results showed that acetylated corn starch enhanced the redness, moisture retention, thickness, and sensory attributes of the patties (P ≤ 0.05). It also reduced the firmness, cooking loss, diameter reduction rate, and dimensional shrinkage of the patties (P ≤ 0.05). The patties contain 15% acetylated corn starch showed a microstructure similar to that contain 15% animal fat as examined by scanning electron microscopy. Patties containing acetylated corn starch showed high scores of physicochemical properties and sensory attributes, which revealed the beneficial use of this modified starch in meat industry. In conclusion, acetylated corn starch improved the physicochemical properties and sensory attributes of beef patties and can thus be used as fat replacer in meat products.

Abstract
Understanding the genetics of drought tolerance in hard red spring wheat (HRSW) in northern USA is a prerequisite for developing drought-tolerant cultivars for this region. An association mapping (AM) study for drought tolerance in spring wheat in northern USA was undertaken using 361 wheat genotypes and Infinium 90K single-nucleotide polymorphism (SNP) assay. The genotypes were evaluated in nine different locations of North Dakota (ND) for plant height (PH), days to heading (DH), yield (YLD), test weight (TW), and thousand kernel weight (TKW) under rain-fed conditions. Rainfall data and soil type of the locations were used to assess drought conditions. A mixed linear model (MLM), which accounts for population structure and kinship (PC+K), was used for marker–trait association. A total of 69 consistent QTL involved with drought tolerance-related traits were identified, with p ≤ 0.001. Chromosomes 1A, 3A, 3B, 4B, 4D, 5B, 6A, and 6B were identified to harbor major QTL for drought tolerance. Six potential novel QTL were identified on chromosomes 3D, 4A, 5B, 7A, and 7B. The novel QTL were identified for DH, PH, and TKW. The findings of this study can be used in marker-assisted selection (MAS) for drought-tolerance breeding in spring wheat.

Abstract
Understanding the genetics of drought tolerance can expedite the development of drought-tolerant cultivars in wheat. In this study, we dissected the genetics of drought tolerance in spring wheat using a recombinant inbred line (RIL) population derived from a cross between a drought-tolerant cultivar, ‘Reeder’ (PI613586), and a high-yielding but drought-susceptible cultivar, ‘Albany.’ The RIL population was evaluated for grain yield (YLD), grain volume weight (GVW), thousand kernel weight (TKW), plant height (PH), and days to heading (DH) at nine different environments. The Infinium 90 k-based high-density genetic map was generated using 10,657 polymorphic SNP markers representing 2,057 unique loci. Quantitative trait loci (QTL) analysis detected a total of 11 consistent QTL for drought tolerance-related traits. Of these, six QTL were exclusively identified in drought-prone environments, and five were constitutive QTL (identified under both drought and normal conditions). One major QTL on chromosome 7B was identified exclusively under drought environments and explained 13.6% of the phenotypic variation (PV) for YLD. Two other major QTL were detected, one each on chromosomes 7B and 2B under drought-prone environments, and explained 14.86 and 13.94% of phenotypic variation for GVW and YLD, respectively. One novel QTL for drought tolerance was identified on chromosome 2D. In silico expression analysis of candidate genes underlaying the exclusive QTLs associated with drought stress identified the enrichment of ribosomal and chloroplast photosynthesis-associated proteins showing the most expression variability, thus possibly contributing to stress response by modulating the glycosyltransferase (TraesCS6A01G116400) and hexosyltransferase (TraesCS7B01G013300) unique genes present in QTL 21 and 24, respectively. While both parents contributed favorable alleles to these QTL, unexpectedly, the high-yielding and less drought-tolerant parent contributed desirable alleles for drought tolerance at four out of six loci. Regardless of the origin, all QTL with significant drought tolerance could assist significantly in the development of drought-tolerant wheat cultivars, using genomics-assisted breeding approaches.

Abstract
Millet flour (water washed or alkali washed) was replaced with wheat flour (WF) at 0, 25, 50, 75, and 100% levels. Objectives of the research were to characterize the flour blends for their technical properties and to produce cookies with less or no gluten contents. All types of flour blends were evaluated for their pasting properties. The cookies were baked and evaluated for their textural and physical attributes. Inclusion of millet flour (both types) in wheat flour resulted in significant reduction in peak and final viscosities while setback viscosities were affected non-significantly. Pasting temperature was increased from 65 ℃ (100% wheat flour) to 91 ℃ (100% millet flour). The hardness of cookies was reduced in the presence of millet flour. Fracturability values of cookies with higher millet flour were higher as compared to control cookies (prepared from 100% wheat flour). Cookies prepared from blends having more that 50% millet flour were not much liked by sensory panelists. The phenolic contents of cookies containing higher levels of either water washed or alkali washed millet flour were found to be higher when compared to cookies prepared from plain WF (1.90 ± 0.14 mg gallic acid/g sample). The 2,2-diphenyl-1-picrylhydrazyl activity (%) of cookies ranged from 16.39 ± 0.34 (100% water washed millet flour) to 10.39 ± 0.26 (100% WF; control). The study will help the non-coeliac people to consume low gluten (≈1.6-6.5%) or gluten intolerant people to consume gluten-free cookies (0%) from millet flour having abundant of antioxidants and health-promoting polyphenols.

Abstract
Wheat kernel shape and size has been under selection since early domestication. Kernel morphology is a major consideration in wheat breeding, as it impacts grain yield and quality. A population of 160 recombinant inbred lines (RIL), developed using an elite (ND 705) and a nonadapted genotype (PI 414566), was extensively phenotyped in replicated field trials and genotyped using Infinium iSelect 90K assay to gain insight into the genetic architecture of kernel shape and size. A high density genetic map consisting of 10,172 single nucleotide polymorphism (SNP) markers, with an average marker density of 0.39 cM/marker, identified a total of 29 genomic regions associated with six grain shape and size traits; ∼80% of these regions were associated with multiple traits. The analyses showed that kernel length (KL) and width (KW) are genetically independent, while a large number (∼59%) of the quantitative trait loci (QTL) for kernel shape traits were in common with genomic regions associated with kernel size traits. The most significant QTL was identified on chromosome 4B, and could be an ortholog of major rice grain size and shape gene or . Major and stable loci also were identified on the homeologous regions of Group 5 chromosomes, and in the regions of (6A) and (7A) genes. Both parental genotypes contributed equivalent positive QTL alleles, suggesting that the nonadapted germplasm has a great potential for enhancing the gene pool for grain shape and size. This study provides new knowledge on the genetic dissection of kernel morphology, with a much higher resolution, which may aid further improvement in wheat yield and quality using genomic tools.

Abstract
In wheat, exotic genotypes harbor a broad range of spike-related traits, and can be used as a source of new genes for germplasm enhancement in wheat breeding programs. In the present study, a population of 163 recombinant inbred lines was derived from a cross between an elite line (WCB414) and an exotic line (WCB617) with branched spike (supernumerary spikelet; SS) head morphology. The population was evaluated over four to six environments to identify quantitative trait loci (QTL) associated with nine spike-related traits and 10 agronomic traits. A genetic map consisting of 939 diversity arrays technology (DArT) markers was constructed. Composite interval mapping identified a total of 143 QTL located on 17 different wheat chromosomes and included 33 consistent and definitive QTL. The amount of phenotype variation explained (PVE) by individual QTL ranged from 0.61 to 91.8%. One major QTL for glume pubescence was located in a QTL-rich region on the short arm of chromosome 1A, where loci for other traits such as for kernels per spike (KS) and spike length (SL) were also identified. Similarly, a cluster of QTL associated with yield-related, agronomic and spike-related traits contributing up to 40.3% of PVE was found on the short arm of chromosome 2D, in the vicinity of a major QTL for SS-related traits. Consistent and major QTL identified in the present study may be useful in marker-assisted breeding programs to facilitate transfer of desirable alleles into other germplasm. Desirable QTL alleles were also contributed by the exotic line, suggesting the possibility of enriching the breeding germplasm with alleles from SS genotypes.

The population was evaluated over four to six environments to identify quantitative trait loci (QTL) associated with nine spike-related traits and 10 agronomic traits. A genetic map consisting of 939 diversity arrays technology (DArT) markers was constructed. Composite interval mapping identified a total of 143 QTL located on 17 different wheat chromosomes and included 33 consistent and definitive QTL. The amount of phenotype variation explained (PVE) by individual QTL ranged from 0.61 to 91.8%. One major QTL for glume pubescence was located in a QTL-rich region on the short arm of chromosome 1A, where loci for other traits such as for kernels per spike (KS) and spike length (SL) were also identified. Similarly, a cluster of QTL associated with yield-related, agronomic and spike-related traits contributing up to 40.3% of PVE was found on the short arm of chromosome 2D, in the vicinity of a major QTL for SS-related traits. Consistent and major QTL identified in the present study may be useful in marker-assisted breeding programs to facilitate transfer of desirable alleles into other germplasm. Desirable QTL alleles were also contributed by the exotic line, suggesting the possibility of enriching the breeding germplasm with alleles from SS genotypes.

Abstract
A population developed from an exotic line with supernumerary spikelets was genetically dissected for eight quality traits, discovering new genes/alleles with potential use in wheat breeding programs. Identifying new QTLs and alleles in exotic germplasm is paramount for further improvement of quality traits in wheat. In the present study, an RIL population developed from a cross of an elite wheat line (WCB414) and an exotic genotype with supernumerary spikelets (SS) was used to identify QTLs and new alleles for eight quality traits. Composite interval mapping for 1,000 kernels weight (TKW), kernel volume weight (KVW), grain protein content (GPC), percent of flour extraction (FE) and four mixograph-related traits identified a total of 69 QTLs including 19 stable QTLs. These QTLs were located on 18 different chromosomes (except 4D, 5D, and 6D). Thirteen of these QTLs explained more than 15% of phenotypic variation (PV) and were considered as major QTLs. In this study, we identified 11 QTLs for TKW (R (2) = 7.2-17.1 %), 10 for KVW (R (2) = 6.7-22.5%), 11 for GPC (R (2) = 4.7-16.9%), 6 for FE (R (2) = 4.8-19%) and 31 for mixograph-related traits (R (2) = 3.2-41.2%). In this population, several previously identified QTLs for SS, nine spike-related and ten agronomic traits were co-located with the quality QTLs, suggesting pleiotropic effects or close linkage among loci. The traits GPC and mixogram-related traits were positively correlated with SS. Indeed, several loci for quality traits were co-located with QTL for SS. The exotic parent contributed positive alleles that increased PV of the traits at 56% of loci demonstrating the suitability of germplasm with SS to improve quality traits in wheat.

Abstract
Freeze-dried okra extract was added to Hard Red Spring (HRS) wheat flour intended for high soluble-fiber bread. Seedless okra pods were blended in 0.05 M NaOH solution and the extract (OE) was freeze-dried at pH 7. SE-HPLC of OE showed the presence of covalently bound peptides. Okra extract powder (OE) 4, 7, 10, and 13 % was used to replace wheat flour in preparing four bread formulations. Although Farinograph water absorption was increased up to 4.4 % due to OE addition, the dough mixing Tolerance (MIT) was also increased. In the presence of OE, bread loaf volume was lower and freezable water was higher. Overall, bread firmness was lower at lower storage temperature, but higher OE increased firmness, due to water migration from crumb to crust. Color was darker for both crust and crumb. The bread melting temperature shifted to lower values at higher OE content as shown by Dynamic Mechanical Analysis (DMA). The test indicated that the properties of the blends were similar around the glass transition region. Dynamic rheology of the blends revealed weaker visco-elastic behavior compared to the control. The magnitude of the complex moduli for the 4 % OE was independent of frequency, while the remaining blends were frequency dependent.

Abstract
BACKGROUND High moisture before harvest can cause sprouting of the wheat kernel, which is termed pre-harvest sprouting (PHS). The aim of this study was to examine the variation in physicochemical properties of proteins in PHS-damaged (sprouted) hard red and white spring wheat genotypes. Specifically, protein content, enzyme activity and degradation of proteins were evaluated in sound and PHS-damaged wheat. RESULTS Protein contents of sprouted wheat samples were lower than that of non-sprouted samples; however, their differences were not significantly (P > 0.05) correlated with sprouting score. Sodium dodecyl sulfate (SDS) buffer extractable proteins (EXP) and unextractable proteins (UNP) were analyzed by high-performance size exclusion chromatography. PHS damage elevated endoprotease activity and consequently increased the degradation of polymeric UNP and free asparagine concentration in wheat samples. Free asparagine is known to be a precursor for formation of carcinogenic acrylamide during high heat treatment, such as baking bread. Free asparagine content had significant correlations (P < 0.01) with sprouting score, endoprotease activity and protein degradation. CONCLUSIONS Genotypes with higher endoprotease activity tend to exhibit a larger degree of degradation of UNP and higher free asparagine concentration in sprouted wheat samples.
